Context.— Granular cell change in melanocytic nevus is underrepresented in the literature with only 4 well-documented cases, 1 described in the conjunctiva. Unfamiliarity with the clinical and pathologic features of these lesions contributes to the diagnostic difficulty. Objective.— To delineate the clinical and histopathologic features of conjunctival nevi with granular cell change. Design.— In a retrospective observational case series, the medical records of all patients with conjunctival nevi and granular cell change diagnosed between December 2016 and October 2018 were reviewed. Data collected included age, sex, clinical presentation, pathologic findings, and follow-up. Results.— Twelve patients, 6 males and 6 females, with a median age of 14 years (range, 8–82 years) were identified. The nevus manifested as a pigmented, well-circumscribed nodule (7 of 9; 78%) or patch (2 of 9; 22%) in the bulbar and limbal conjunctiva (7 of 9; 78%) or in the plica semilunaris/caruncle (2 of 9; 22%). Cysts were noted in 7 of 9 lesions (78%). Features prompting surgical excision included atypical pigmentation (8 of 9; 89%), growth (7 of 9; 78%), and atypical vascularity (4 of 9; 44%). Microscopically, all lesions comprised a conventional melanocytic nevus with focal granular cell change and immunoreactivity for Melan-A, SOX10, and HMB-45, with Ki-67 proliferative index of less than 2%. Of the 9 lesions with follow-up information, there were no recurrences over mean follow-up of 11.2 months (range, 1–23 months). Conclusions.— Granular cell change in melanocytic nevi is an underrecognized finding that can simulate melanoma clinically and histopathologically. Young age at diagnosis, lack of associated conjunctival melanosis, bulbar location, cysts, and the absence of mitotic figures with a low Ki-67 proliferative index are helpful clinical and pathologic diagnostic clues.

Background: Congenital granular cell epulis (CGCE) is an extremely rare intraoral tumor of the newborn with a potential to disrupt feeding and produce respiratory distress. Case Series: We report two newborns presented with mass protruding off the mouth since birth. The mass was arising from alveolar ridge in both cases and dealt with surgical excision. Histopathology revealed it congenital granular cell epulis. Postoperative recovery and follow-up are uneventful. Conclusion: Congenital granular cell epulis is a benign lesion though not quite uncommon, may cause diagnostic challenges. Early excision and histopathology rule out malignant lesions.

Purpose:  To find out the demographics, presentation, and outcome of surgical treatment in patients of orbital hydatid cyst. Study Design:  Interventional case series. Place and Duration of Study:  Khyber Teaching Hospital Peshawar, Pakistan from 2009 to 2019. Methods:  This study included 11 patients with orbital hydatid cyst who presented in Khyber Teaching Hospital, Peshawar. Detailed history, ocular examination and Orbital imaging (Ophthalmic B-Scan, CT scan and/or MRI) was performed. The patients underwent Orbitotomy, cyst extirpated and sent for histopathology. Albendazole was given to the patients for 12 weeks after surgery. The preoperative and postoperative data until last follow-up was analyzed. Results:  Male to Female ratio was 5:6 and the mean age of the patients was 18.17 ± 17.4 years. Mean amount of proptosis was 26.27 ± 2.05mm and visual acuity was 0.23 ± 0.33 decimal in the affected eye at presentation. Eight patients (72.8%) had Relative Afferent Pupillary Defect with swollen discs. After imaging studies, presumptive diagnosis of hydatid cyst was made. Histopathology confirmed the diagnosis of hydatid cyst in all cases. Mean proptosis at the last follow up improved to 19.04 ± 1.45mm (P value = 0.00) and visual acuity to 0.47 ± 0.22 decimals (P value = 0.048). Only one patient (9.1%) had an associated hydatid cyst in the lung. There was no recurrence until last follow-up. Conclusion:  Hydatid cyst should be considered in differential diagnosis of proptosis in patients under 20. Surgical excision followed by a course of oral Albendazole is effective for the treatment of orbital hydatid cyst. Key Words:  Orbital hydatid cyst, Proptosis, Orbitotomy.

Objective: To evaluate the status of C-MYC protein expression and Ki-67 proliferative index and to clarify their role in predicting relapse of diffuse large B cell lymphoma (DLBL). Materials and Methods: A retrospective study conducted on 50 cases diagnosed as DLBL in a 3 years’ time period from January 2014 till December 2016, collected from the archive of Pathology Departments of the National Cancer Institute Cairo - Egypt, Misr University for Science and Technology and private labs of authors. The diagnosis of DLBL for all cases, both nodal and extranodal, was confirmed by histopathologic examination and immunophenotyping. Automated immunohistochemical staining using antibodies against C-MYC protein and MIB-1 was used to evaluate the C-MYC expression in tumor cells and to assess their proliferative ability by calculating Ki-67 labelling index. The relation between the percentage of C-MYC protein expression, Ki-67 proliferative index, clinical data and the relapse status during the follow up period were analyzed. Results: A total of 50 cases of DLBL in both nodal and extra-nodal sites were included. Twenty-three cases (46%) were expressing the C-MYC protein, and 29 cases (58%) showed high Ki-67 proliferative index. Twenty-two cases (44%) relapsed during the follow-up period. Positive C-MYC protein expression was significantly associated with high Ki-67 proliferative index. C-MYC protein expression and high Ki-67 proliferative index were independently associated with disease relapses in 81.8% and 86.4% of cases respectively. Cases with combined C-MYC protein expression and high Ki-67 proliferative index showed statistical prediction of relapse in 81.8% of cases. Conclusion: C-MYC protein expression and high Ki-67 proliferative index were independently associated with relapse of diffuse large B cell lymphoma. Furthermore, the combined positive C-MYC protein expression and high Ki-67 proliferative index is better than a single positive test in predicting relapses among DLBL patients.

A retrospective case review was carried out to report the outcomes in a contemporary case series of Ewing’s sarcoma originating in the hand. We identified five patients treated since 1995. All five had wide surgical excision, one by ray amputation. All were treated with chemotherapy. Four patients also received radiation therapy, two to treat metastases and two as an adjunct to local excision. There were no local recurrences. Two patients developed metastases. Both died of their disease. Neither of these two patients had received local postoperative radiation therapy; one did not receive chemotherapy before definitive surgery. The other three patients were alive and free of disease at last follow-up, 4 to 12 years after initial presentation.

AbstractThe diagnosis of primary angiosarcoma of ovary is still a challenge as it has no specific clinical symptoms and is easily confused with other malignant neoplasms in morphology. Here, we described a case of primary ovarian angiosarcoma and reviewed the literature. A 47-year-old female showed a left ovary mass. Grossly, the cut surface of the tumor was solid and gray-white with intermediate texture. Some areas were spongy and atropurpureus with a soft texture. Microscopically, the tumor cells were arranged into a variety of different structures with visible hemorrhage. Immunochemically, the tumor cells were positive for CD31, ERG, Fli1, D2–40 and vimentin in a strong and diffused manner. CD34 stain showed focal positivity. Epithelial markers (e.g. CK, CK7, CK8/18 and PAX8) were all negative. Negative immunostaining for SMA, S-100, P53 and calretinin also were detected. The proliferative index (Ki-67) was approximately 40%. After surgery, the patient was treated with radiotherapy, targeted therapy and immunotherapy. In the 9-month follow-up, the patient was survival without evidence of disease. The diagnosis of ovarian angiosarcoma required the careful observation of morphology and the reasonable application of immunohistochemistry. Targeted therapy and immunotherapy are the potential directions for the treatment of angiosarcoma.

Nowadays, neither imaging nor pathology evaluation can accurately predict the aggressiveness or treatment resistance of pituitary tumors at diagnosis. However, histological examination can provide useful information that might alert clinicians about the nature of pituitary tumors. Here, we describe our experience with a silent corticothoph tumor with unusual pathology, aggressive local invasion and metastatic dissemination during follow-up. We present a 61-year-old man with third cranial nerve palsy at presentation due to invasive pituitary tumor. Subtotal surgical approach was performed with a diagnosis of silent corticotroph tumor but with unusual histological features (nuclear atypia, frequent multinucleation and mitotic figures, and Ki-67 labeling index up to 70%). After a rapid regrowth, a second surgical intervention achieved successful debulking. Temozolomide treatment followed by stereotactic fractionated radiotherapy associated with temozolomide successfully managed the primary tumor. However, sacral metastasis showed up 6 months after radiotherapy treatment. Due to aggressive distant behavior, a carboplatine-etoposide scheme was decided but the patient died of urinary sepsis 31 months after the first symptoms. Our case report shows how the presentation of a pituitary tumor with aggressive features should raise a suspicion of malignancy and the need of follow up by multidisciplinary team with experience in its management. Metastases may occur even if the primary tumor is well controlled.

Immunohistochemical Assessment

Abstract Context.—Granular cell tumor (GCT) is a rare tumor of nerve sheath origin with a predilection for upper aerodigestive tract, skin, and soft tissue. The neoplastic cells typically express S100 and CD68 (KP-1), the latter due to cytoplasmic lysosome content. However, the histogenesis of this tumor is unknown. Additionally, distinction between benign and malignant GCT is difficult because of histologic similarity and lack of reliable criteria that can predict clinical behavior. Objective.—To perform a comparative, side-by-side immunohistochemical assessment of the traditional immunohistochemical markers for GCTs (S100, CD68), along with the newer markers (inhibin-α, protein gene product 9.5) for these tumors. Design.—To address diagnostic and prognostic issues, we studied 30 specimens of GCT (27 primary and 3 recurrent tumors, 2 of which occurred consecutively in the same patient) for (1) nuclear pleomorphism, prominent nucleoli, necrosis, spindling, high nuclear-cytoplasmic ratio, and mitoses; (2) immunohistochemical expression of inhibin-α, protein gene product 9.5, S100, CD68 (KP-1), and Ki-67 using the avidin-biotin complex method on formalin-fixed, paraffin-embedded sections; and (3) correlation between tumor grade, proliferative fraction, and clinical data. Results.—Twenty-seven of 27 primary GCTs and 1 of 3 recurrent GCTs had typical histologic features, while the 2 consecutive recurrent GCT specimens from the same patient were atypical (moderate nuclear atypia and prominent nucleoli alone). The mean age for primary GCT was 37.3 years (range, 5–67 years), and mean size was 1.89 cm. None of the cases metastasized. All 30 specimens showed diffuse (2+ to 3+) staining for S100, CD68, and inhibin-α, and 3+ staining for protein gene product 9.5; pseudoepitheliomatous hyperplasia was nonreactive. The Ki-67 proliferative index was less than 1% to 20% in typical nonrecurrent cases, 1% in the typical recurrent case, and 1% and 10% in 2 sequential recurrences of the atypical case. Conclusion.—Our study expands the immunophenotype of GCT (S100, CD68, protein gene product 9.5, and inhibin-α) regardless of location and supports a neural origin. Intensity of immunohistochemical staining had no prognostic significance. Although 1 of the 2 recurrent GCTs had atypical features, the Ki-67 proliferative index did not distinguish reliably between typical (nonrecurrent) and atypical or recurrent GCTs. The significance of inhibin expression with regard to cell differentiation and pathogenesis is unclear and warrants further investigation.

Histologic Changes

Chondroblastoma is a rare benign tumor of immature cartilage cells that generally occurs in an epiphyseal location of skeletally immature individuals. However, a few studies have reported cases in older patients. The purpose of this study was to evaluate the clinical, radiographic, and pathologic features of chondroblastoma in an adult population. The pathology archives of our institution were searched for cases of chondroblastoma diagnosed in patients ≥25 years of age. Of 14 patients identified, 8 were male and 6 were female with a median age of 34 years (range = 29-54 years). Most lesions occurred in short bones of hands and feet (N = 7, 50%), followed by the long tubular bones (N = 4, 28%). All demonstrated typical histologic features of chondroblastoma, but more extensive calcification, necrosis, and degenerative changes were also seen. At follow-up (median = 73.5 months), 2 patients (17%) had local recurrence. None had metastasis. In summary, chondroblastoma in adults tends to involve the short bones of the hands and feet and demonstrate histologic changes associated with long-standing growth of a benign tumor.

Cardiac Myxomas

Abstract Background Cardiac myxomas are rare, despite being the most common primary cardiac tumours. A significant number of myxomas are discovered accidentally in asymptomatic patients (pts), as there is increased use of non-invasive cardiac imaging. Our aim was to describe the experience of a cardiac surgery centre managing cardiac myxomas during the last 28 years. Methods Single-center retrospective study of consecutive pts admitted with the diagnosis of a cardiac myxomas between 1990 and 2018. Registry data concerning clinical presentation, non-invasive imaging assessment and definitive histopathology were collected. Results From 154 pts with the diagnosis of cardiac tumours, we identified 106 (68.8%) myxomas (67% females; mean age at diagnosis 61,5±13,1 years). Myxoma diagnosis increased throughout the 3 decades (27 cases until 2000; 26 cases in the second decade; 52 cases from 2010 until present). 30% of the pts were asymptomatic at diagnosis. Obstructive symptoms (heart failure and syncope) and embolic events were the most common complaints among symptomatic pts. Transthoracic echocardiography firstly identified the tumours in 88% of the cases. Cardiac magnetic resonance and computed tomography were performed for further investigation in 7% of the cases. Presumptive pre-operative diagnosis was correct in 83.8% pts. Surgical excision was successfully achieved in all cases. 89% of the tumours were located in the left atrium with inter-atrial septum implantation (13 in right chambers; 1 valvular tumour). There were 10 multifocal tumours. At histopathology myxomas were grossly described as mucous jelly appearance (80%), solid (15%) and mixed type lesions (5%). Rare histologic findings were described in 30% of the cases (8 tumours with bone tissue; 1 with forming bone marrow; 4 with endocrine type glandular epithelium; 16 with lympho-plasmocytic infiltrates; 3 with high mitotic grade; 5 with concomitant thrombus). For a median follow up of 86 [31–214] months there were 15 deaths (2 of them with tumour related deaths). There were 3 recurrences (2 with high mitotic grade histology), mostly occurring 3 years after the first intervention. Conclusion In this case series cardiac myxomas are the most common cardiac tumours, with a significant proportion of asymptomatic lesions. Clinical heterogeneity followed polymorphic histology, with recognized differences when compared to classical descriptions of this kind of tumour.

Introduction Granular cell tumor was first described by Abrikossoff in 1926. Over the years several cases of this neoplasm have been reported, with a variety of localizations. We here report a case of perianal granular cell tumor and discuss its histogenesis and its relevance to clinical practice. Methods The clinical course and histopathology of the case are reviewed, and a literature search for other reported cases has been performed. Results A 46-year-old woman presented with a perianal nodular lesion. Pathological examination revealed a granular cell tumor. A literature search produced only 25 other cases of anal and perianal granular cell tumors. Conclusions Granular cell tumors are rarely observed in the perianal region. Their existence must always be borne in mind in the differential diagnosis of perianal neoplasms. In most cases surgical excision is curative, but potential malignant transformation must be considered during therapeutic procedures and follow-up.
