A 75-year-old woman presented with a ganglion-like nodule on the dorsal aspect of the right foot. A 2.5 × 1.5 cm, saccular and malleable tumor, that was in continuity with the dorsal venous arch, was completely resected. It was characterized by a diffuse intramural and circumferential, low grade, malignant, smooth muscle proliferation with an aneurysmal-like luminal space. No endoluminal or periadventitial invasive neoplastic component was present. The patient had no evidence of disease at 58-month follow-up. This is the first reported case of venous leiomyosarcoma in the foot. Furthermore, the intramural confinement of neoplastic growth is a unique observation.

Case summary A 6-month-old female Bengal cat was referred for a suspected vegetal foreign body (FB) in the mid-stroma of the right cornea. A small dark linear FB was identified in the dorsal aspect of the cornea, with associated cell infiltrate. Ophthalmic examination was otherwise normal, with no inflammatory reaction of the anterior uvea, and no abnormalities of the lens or fundus. Surgical removal was performed under general anesthesia. The FB, as observed under an optic microscope, was a worker bee stinger without the venom sac. Medical treatment consisted of topical and systemic antibiotics and steroids, and topical administration of atropine. Follow-up was uneventful. Relevance and novel information Ocular bee stings have been described in humans, with several consequences ranging from mild conjunctivitis to severe lesions affecting the cornea, iris, lens and retina. Most severely affected cases have been observed when the venom sac was found with the stinger, with a likely greater amount of venom being delivered into the ocular structures. The relatively benign presentation of this case was probably due to the lack of the venom sac within the bee sting. To our knowledge, this is the first documented case of a corneal bee sting in a cat.

Despite being one of the most frequent soft-tissue sarcomas, well-differentiated liposarcoma has never been reported near the spine. The authors present the case of a 67-year-old man with progressive history of back pain. Physical examination revealed a mass located within the right paravertebral muscles. MR and CT imaging showed a heavily ossified central mass surrounded by a peripheral fatty component. No connection with the underlying bone was detected on imagery and during surgery. After surgical resection, histopathological examination revealed a tumor harboring combined features of well-differentiated liposarcoma and low-grade osteosarcoma. Tumor cells displayed overexpression of MDM2, CDK4, and P16 by immunohistochemistry and CGH revealed amplification of 12q13-15 as the only genetic imbalance. MDM2 FISH analysis was performed but was inconclusive. The pathological, immunohistochemical, and genetic features, the differential diagnoses, and the therapeutic management of this unusual tumor are discussed. No complementary treatment was performed initially. Following first treatment, two recurrences occurred 6 and 9 years later, both displaying histological features similar to the first occurrence. Radiotherapy was started after the second recurrence. Follow-up shows no evidence of disease 11 years after initial diagnosis. This case was unusual due to the paravertebral location of the tumor and its divergent differentiation.

15028 Background: Smooth muscle tumors of uncertain malignant potential (STUMP) and atypical leiomyomas have increased mitotic activity, cellular atypia and necrosis but the degree is less than that used to define uterine leiomyosarcomas. Our objective is to evaluate the clinical outcome of patients with uterine masses histologically defined as smooth muscle tumors of uncertain malignant potential or atypical leiomyomas. Methods: A thorough search of our institution’s pathology database from 1990 to 2005 was performed. A retrospective chart review was performed to obtain initial and subsequent treatments, documented recurrences and clinical outcomes. Pathology reports and slides were reviewed and the presence of atypia, necrosis and number of mitosis was recorded. Statistical analysis was performed by Student’s T-test. Results: Eighteen patients with a histologic diagnosis of atypical leiomyoma were identified with 14 STUMP, 2 bizarre leiomyomas, 1 myxoid and 1 mitotically active leiomyoma. The mean age of these patients was 41.8 years (range: 25–77) and was significantly younger than those with leiomyosarcoma (mean age was 54 years, p < 0.001). The histologic characteristics of the tumors included the presence of atypia at 50%, necrosis at 82% and mitoses at 94%. The rate of necrosis and number of mitosis was significantly less in the atypical group as compared to the leiomyosarcoma group (p values < 0.05). However the rate of cellular atypia was not statistically different between the two groups. The median follow-up period was 25 months, range 1–138 months. One of the eighteen patients developed a pelvic and pulmonary recurrence at which time a low grade leiomyosarcoma was diagnosed. The recurrence occurred 32 months after the initial diagnosis of a mitotically active leiomyoma. Sixteen patients demonstrated no recurrence or metastatic disease at the time of follow-up. Conclusions: Atypical leiomyomas appear to be diagnosed in younger women which leads to challenging treatment issues involving fertility preservation. While these tumors generally behave in a benign fashion, they have histologic characteristics that may allow for progression or recurrence. Close follow-up is warranted for patients who are diagnosed with atypical leiomyomas and smooth muscle tumors of uncertain malignant potential. No significant financial relationships to disclose.

Leiomyomas are rare benign tumors that grow in the tunica media of smooth muscle cells. Leiomyomas occur most frequently in the uterus or gastrointestinal tract and only very rarely in the area of the cheek. This study reports on a rare case of a leiomyoma in the cheek of a 43-year-old woman, who presented with a well-circumscribed, asymptomatic, mobile swelling in the right cheek. This swelling was slightly purplish in color and measured approximately 4 cm×3 cm. Surgical excision was the treatment of choice, and the diagnosis was based on histopathological and immunohistochemical stains, which were positive for actin and desmin and negative for AE1/AE3, CD34, and S100. The patient’s follow-up, two years later, showed no recurrence, and she has been asymptomatic since the surgery.

Abstract Introduction/Objective Primary tumors of the heart are uncommon; even rarer are primary cardiac neuroendocrine tumors. To our knowledge, only two cases have been described to date, both being high-grade tumors. We report a solitary low-grade neuroendocrine tumor of the heart, unexpectedly discovered on the wall of the right ventricle in a 44-year-old man during aortic valve repair for infectious bacterial endocarditis. Results Frozen section was sent intraoperatively and showed a plasmacytoid neoplasm. Final pathology of the biopsies showed a tumor composed of both cohesive and discohesive plasmacytoid cells separated by a vascular network and strands of fibrosis. Neither necrosis nor a mitotic rate greater than 2 mitoses per 2 mm2 were seen. The tumor showed strong reactivity for AE1/3, synaptophysin and CDX2 with focal reactivity for chromogranin-A and CD56, confirming the diagnosis of a low-grade neuroendocrine tumor. Both an esophagogastroduodenoscopy and colonoscopy were performed and showed no evidence of a primary gastrointestinal tumor. PET-CT DOTATATE performed after complete resection of the tumor showed no abnormal radiotracer uptake. The possibility of an intestinal neuroendocrine tumor undetected by DOTATATE PET-CT with a single known metastasis to the heart was considered. This too, on the basis of the literature, was considered exceedingly rare. Complete resection of this patient’s tumor was considered sufficient treatment; the patient was advised to follow up annually with medical oncology. Conclusion The presentation and management of a solitary cardiac low-grade neuroendocrine tumor has not previously been described in the literature.

Leiomyoma is a rare, smooth muscle tumour that can occur everywhere in the human body. The authors present the history of a 60-year-old female, who had a giant, Mullerian type myxoid leiomyoma in the inguinal region mimicking acute abdominal symptoms. After examination the authors removed the soft tissue mass in the right femoral region reaching down in supine position to the middle third of the leg measuring 335 × 495 × 437 mm in greatest diameters in weight 33 kg. Reconstruction of the tissue defect was performed using oncoplastic guidelines. During the follow-up time no tumour recurrence was detected and the quality of life of the patient improved significantly. Orv. Hetil., 2016, 157(10), 392–395.

Adamantinoma is a rare, low-grade malignant tumor of the bone which grows slowly and typically occurs in the diaphysis of long bones, particularly in the tibia. Adamantinomas have the potential for local recurrence and may metastasize to the lungs, lymph nodes, or bone. We report a case of a 14-year-old female with a tibial adamantinoma who underwent wide resection with limb salvage and has subsequently been followed up for 18 years. The patient went on to have both a local soft tissue recurrence 5 years after the resection and metastases to both an inguinal lymph node and the right lower lobe of the lung 8 years after that recurrence, all of which have been treated successfully with marginal resections. Unique to this case, the patient was also incidentally found to have chromophobe-type renal cell carcinoma when undergoing a partial nephrectomy to resect a presumed metastasis of her adamantinoma. Genetic testing has not revealed any known genetic predisposition to cancer.

Abstract Background Patients with inflammatory bowel diseases (IBD) are at increased risk of dysplasia and colitis-associated cancer (CAC). The presentation of (pre)neoplastic lesions (low-grade dysplasia (LGD), high-grade dysplasia (HGD) or colorectal cancer (CRC) is reported to vary depending if the lesions are located inside disease area (IDA) or outside diseased area (ODA). The primary aim was to analyse the characteristics and prognostic of IDA compared with ODA neoplastic lesions in a large cohort of IBD patients. Methods We performed a multicentre retrospective pathological data collection from 7 tertiary referral regional or academic IBD centres in Belgium. Clinical, endoscopic and pathological data were retrieved through retrospective electronic chart review. From the IBD pathology databases, 1183 colorectal lesions were identified in 541 IBD patients: 415 developed dysplasia (77%) and 126 CRC (23%) during their follow-up. Biopsies and surgical specimen were centrally reviewed by an expert IBD pathologist to confirm the diagnosis of dysplasia and/or CRC. Results Demographic and clinical variables of the study population are summarised in Table 1. More patients with IDA lesions had HGD (9%) or CAC (27%) during their follow-up compared with the group of patients with ODA lesions (3% of HGD and 11% of CRC) (p &lt; 0,0001). Mortality was higher in patients with IDA than in those with ODA lesions (p &lt; 0.05). When comparing IBD patients with IDA lesions and CAC (=111) to those with ODA lesions and sporadic CRC (n = 15), median age at IBD diagnosis was lower (29 (IQR:22–49) vs. 41(IQR:28–54) years; p = 0.0001). Characteristics of the 1183 neoplastic lesions are summarised in Table 2. IDA lesions were more frequently non-visible, non-polypoid and ≥ 1 cm than ODA lesions (p &lt; 0.0001). ODA sporadic CRC was more frequently located in the right colon compared with IDA CAC (5/16 (31%) vs. 21/133 (16%), p &lt; 0.01). Conclusion Neoplastic lesions outside the diseased area were more likely to be visible, polypoid, &lt; 1cm, in the right colon and diagnosed at endoscopy than inside disease area lesions. A lower prevalence of HGD and Cancer were reported with neoplastic lesions outside the diseased area.

Endometrial stromal sarcomas of uterus are quite rare. Most of the recurrences in these tumors are seen in the pelvis. However, extrapelvic recurrences and metastases to other parts are quite unusual. Here, we are reporting a rare case of caecal recurrence of endometrial stromal sarcoma. Case Report. A 52-year-old female presented to us with pain and lump in the right lower abdomen. The patient was earlier subjected to total abdominal hysterectomy with bilateral salpingo-oophorectomy (TAHBSO) for low-grade endometrial stromal sarcoma. Postoperatively patient received radiotherapy but no hormone therapy. After 10 years of follow up patient presented with a polypoidal lesion in the caecum. Patient was evaluated fully and subjected to resection of this polypoidal lesion, which proved out to be high-grade endometrial stromal sarcoma. Conclusion. Recurrence of endometrial stromal sarcoma in the caecum is very rare. However, this entity needs to be kept in mind for differential diagnosis of a caecal mass. Recurrence in such cases may present quite late.

Angiomyxoma is a rare slow-growing, benign low-grade tumor occurring in women of reproductive age group which is known for its recurrence. The symptoms are variable. Mrs. K. aged 33 years, reached our outpatient department (OPD) with complaints of painless swelling on the right labial region which she was feeling uncomfortable while sitting. Mass was found to be mobile with no evidence of inflammatory change. The location of the mass made us think about, Bartholin’s cyst and hence surgical excision of the mass was done. The whole mass was found to be lying below the fat in the right labial region and wide excision was completed. The histopathology of the mass was reported as angiomyxoma. Angiomyxoma arises from the mesenchymal tissue and it is locally invasive with high recurrence rate. It is more common in females. Mostly seen in the vulvovaginal, pelvic cavity and perineum. The lesion can reach huge size. It has to be differentiated from gynecologic malignancies, cyst, abscess and hernia. Histology along with immune-histochemistry can confirm the lesion. Wide excision is the mode of treatment. Incomplete excision can lead to relapse. Relapse can happen in 35-72% of the cases. Local recurrence may occur between 2 months to 15 years following initial diagnosis. Hence, follow up is essential. Angiomyxoma is a very rare condition and only around 250 cases have been reported in the world literature. It has to be differentiated from other benign conditions. Diagnosed by non-invasive techniques like ultrasound sonography (USG), magnetic resonance imaging (MRI) and computed tomography (CT). Wide excision is the treatment of choice. Long term follow up is needed as recurrences are high.
