Abstract Background Adenomatoid tumors (AT) are benign neoplasms of mesothelial origin that occur more frequently in the genital tracts. In uterus, AT are usually located in the subserosa of the cornual myometrium. Microscopically, it is characterized by interanastomosing pseudoglands or pseudovascular spaces and striking smooth-muscle hypertrophy is often present. In some cases, the prominence of smooth muscle component simulates a leiomyoma and the lesion is denoted as a leiomyoadenomatoid tumor. The microscopic appearance of the adenomatoid component (AC) may mimic a malignant tumor due to irregular pseudoinfiltration with tubular formations. Just 16 cases with this morphological presentation were found in the literature review. Case presentations The first case, a 38-year-old female, showed lower abdominal pain, menorrhagia, postcoital bleeding and previous history of uterin leiomyoma. The second case, a 26-year-old female, had clinical complaint of metrorrhagia and received diagnostic hypothesis of leiomyoma after ultrasound image. Both underwent myomectomy. Microscopically, the uterine masses showed intersecting smooth muscle bundles and gland like areas lined by cuboidal epithelioid cells that stained positive for WT1, D2–40 and calretinin in immunohistochemical analysis. Conclusions The cases were diagnosed as leiomyoadenomatoid tumor of the uterus. This is a benign and rare entity that may mimic malignant tumors due to the pseudo infiltrative appereance of the adenomatoid component, possibly leading to misdiagnosis.

Abstract Background Parathyroid carcinoma is a rare endocrine malignancy, rarer when synchronous with a non medullary well differentiated thyroid carcinoma. Parathyroid carcinoma accounts of 0.005% of all malignant tumors and it is responsible for less than 1% of primary hyperparathyroidism. The intrathyroidal localization of a parathyroid gland is not frequent with a reported prevalence of 0.2%. Carcinoma of parathyroids with intrathyroidal localization represents an even rarer finding, reported in only 16 cases described in literature. The rare constellation of synchronous parathyroid and thyroid carcinomas has prompted us to report our experience and perform literature review. Case presentation We herein report a case of a 63-years-old man with multinodular goiter and biochemical diagnosis of hyperparathyroidism. Total thyroidectomy with radio-guide technique using gamma probe after intraoperative sesta-MIBI administration and intraoperative PTH level was performed. The high radiation levels in the posterior thyroid lobe discovered an intrathyroidal parathyroid. Microscopic examination revealed a parathyroid main cell carcinoma at the posterior thyroidal left basal lobe, a classic papillary carcinoma at the same lobe and follicular variant of papillary carcinoma at the thyroidal right lobe. To the best of our knowledge, this is the first case documenting a synchronous multicentric non medullary thyroid carcinomas and intrathyroidal parathyroid carcinoma. Conclusions Our experience was reported and literature review underlining challenging difficulties in diagnostic workup and surgical management was carried out.

Objective: To report a case of herpes virus-associated nasopharyngitis in an adult patient. Methods: The patient’s medical record was reviewed for demographic and clinical data. For literature review, all case reports or other publications published in English literature were identified using Pubmed with the MeSH terms “herpes,” “nasopharyngitis,” and “upper respiratory infection.” Results: A 40-year-old male presented for nasal congestion and a suspected nasal mass. Computed tomography of the sinuses revealed edematous changes in the nasopharynx which exerted a downward mass effect at the right aspect of the soft palate. Flexible fiberoptic laryngoscopy (FFL) revealed a lesion arising from the posterior aspect of the soft palate with extension into the posterior nasal cavity as well as copious mucopurulent secretions consistent with a superimposed acute sinusitis. Rigid nasal endoscopy demonstrated a friable and ulcerated lesion arising from the aforementioned anatomical location. Biopsy of this lesion and subsequent immunohistochemical analysis revealed a diagnosis of herpetic nasopharyngitis. Conclusions: Herpetic infection should be in the differential diagnosis of patients presenting with atypical symptoms of nasopharyngitis. Early accurate diagnosis and appropriate specific management can limit the duration of disease course and prevent further complications.

Desmoid tumors (deep fibromatosis) of the mesentery are rare mesenchymal tumors. They are often misdiagnosed, especially with a previous history of resection for gastrointestinal stromal tumor (GIST). Immunohistochemistry can help differentiate between these two tumors. In this article, we present a case we had encountered: a Desmoid tumor developing in a patient with a history of GIST 3 years ago. It is the first case of GIST with subsequent development of Desmoid tumor to be reported in Saudi Arabia. We discuss the two entities of Desmoid tumor and GIST by comparing their definitions, clinical presentations, histological features, immunohistochemistry stains, molecular pathogenesis, prognosis, and treatment. We also discuss the relationship between GIST and the subsequent development of Desmoid tumors and compare our case with case reports in literature.

Purpose To report two cases of polymicrobial keratitis following corneal collagen cross-linking for keratoconus and to review the literature. Methods Retrospective case note and literature review. Results The first case involved a 27-year-old male who presented with amebic corneal ulcers 3 days after the collagen cross-linking procedure. Some gram-negative (gram-ve) cocci were found upon staining, and cysts were observed by confocal microscopy at 7 days after surgery. Acanthamoeba infection mixed with gram-ve organisms was diagnosed. In the second case, a 14-year male developed Staphylococcus aureus corneal infection with anterior chamber empyema 3 days after the collagen cross-linking procedure for keratoconus. Occasional gram-positive (gram + ve) cocci and gram-ve bacilli were observed under a microscope. The mixed keratitis in the two patients resolved after systemic and topical antibiotic therapy, but the infection ultimately resulted in corneal scarring. Follow-up keratoplasty was needed to improve vision acuity in both patients. Conclusion Although ultraviolet irradiation and the reactive oxygen released by riboflavin during collagen cross-linking have bactericidal effects, a lack of a corneal epithelial barrier, bandage contact lens usage, perioperative hygiene, and an abnormal immune state are risk factors for infectious keratitis after collagen cross-linking. Perioperative management of collagen cross-linking is important to prevent infection.

Uterine lipoleiomyosarcoma is a heterologous sarcoma composed of variable proportions of malignant lipoblasts histologically corresponding to well differentiated liposarcoma and malignant smooth muscle cells corresponding to leiomyosarcoma. Finding of benign lipomatous component in a typical leiomyoma (lipoleiomyoma) is not an uncommon, however, lipoleiomyosarcoma is an extremely rare malignant tumor and only very few cases have been reported so far. We report a case of lipoleiomyosarcoma of uterine corpus in a postmenopausal woman presenting with lower abdominal pain and abdominal mass. Diagnosis of lipoleiomyosarcoma was confirmed by histopathological examination of hysterectomy specimen. This is the first case of lipoleiomyosarcoma of uterus reported from Nepal. Keywords: Lipoleiomyosarcoma, uterus, histopathology, unusual case.   doi:10.3126/njog.v2i1.1482    N. J. Obstet. Gynaecol Vol. 2, No. 1, p. 67 - 70 May -June 2007

Adenomyomas are benign tumors composed of smooth muscle and endometrial tissue. These tumors usually arise from the myometrium. Extrauterine adenomyomas are rare with only a few case reports available in the literature. Here, we report an unusual case of multiple adenomyomas in a 39-year-old woman six years after hysterectomy for multiple leiomyomata. To the best of our knowledge, this is the first case of extrauterine adenomyoma presenting as an upper abdominal mass.

Primary central nervous system (CNS) tumors represent the most common solid tumors in childhood. Ependymomas arise from ependymal cells lining the wall of ventricles or central canal of spinal cord and their occurrence outside the CNS is extremely rare, published in the literature as case reports or small case series. We present two cases of extra-CNS myxopapillary ependymomas treated at our institution in the past three years; both cases originate in the sacrococcygeal region and were initially misdiagnosed as epidermoid cyst and germ cell tumor, respectively. The first case, which arose in a 9-year-old girl, was treated with a surgical excision in two stages, due to the non-radical manner of the first operation; no recurrence was observed after two years of follow-up. The other case was a 12-year-old boy who was treated with a complete resection and showed no evidence of recurrence at one-year follow-up. In this paper, we report our experience in treating an extremely rare disease that lacks a standardized approach to diagnosis, treatment and follow-up; in addition, we perform a literature review of the past 35 years.

AbstractIntroduction:Craniofacial fibrous dysplasia commonly affects the larger mandible and the maxillary bones. Although involvement of the frontal, temporal and sphenoid bones has been described, fibrous dysplasia of the nasal bone has not been previously described; the two cases reported here have been made rarer by their isolated involvement. Clinical management is dependent on disease activity and patient symptoms.Objective:To present two cases of isolated fibrous dysplasia of the nasal bone: a 46-year-old woman with gradual widening of the nasal bridge and a 47-year-old man with an incidental finding of a nasal bone mass.Method:Two case reports.Results:The 46-year-old woman underwent excision of the lesion while the 47-year-old man opted for watchful waiting.Conclusion:We have presented the first case reports of fibrous dysplasia of the nasal bone. The care of these patients should be customised to their needs and wishes.

Introduction Extravasation is a rare complication from intravenous chemotherapy administration. Literature about monoclonal antibody (MoAb) extravasations is scarce and also conflicting in how they are classified. Case report We reported two different cases of MoAb extravasations with cetuximab and nivolumab outcome respectively. The administration site appeared inflamed and patients did not report disturbances. Management and outcome: Both extravasations did not require specific treatment. General unspecific measures suffice to properly manage these extravasations and no sequels were observed after long follow-up. Both patients received all further courses of MoAb without any adverse events. Discussion To our knowledge, we reported the first case-report of nivolumab extravasation in the literature. In addition, the cetuximab extravasation management and outcome was in accordance with previously published reports. Both MoAb may be considered as non-aggressive or neutral. We reviewed published information about MoAb extravasations. In conclusion, not all MoAb should be classified in the same category when extravasated and special precautions are warranted with conjugated MoAb and bevacizumab.

Angiomyolipoma is an extremely rare neoplasm in animals. It belongs to a group of perivascular epithelioid cell tumours (so-called PEComas). This study reports a case of primary soft tissue angiomyolipoma in a dog with some unusual clinical features. A 4-year old female Labrador dog with a rapidly growing pelvic tumour measuring 30 × 20 cm with a short history of 12 weeks was presented. The tumour was well-circumscribed and pushed into the right vaginal wall and into the perineum. The tumour was completely surgically excised. An extensive histological examination was performed, including immunohistochemical analysis. Histology revealed a mesenchymal neoplasm consisting of three tissue components – mature adipose tissue (which dominated), vessels, and smooth muscle (spindle) cells. The lesion showed positive immunohistochemical staining with smooth muscle actin and desmin in mature-appearing smooth muscle cells and S-100 protein positivity in adipocytes. The diagnosis of angiomyolipoma must be considered in different types of benign and malignant tumours of various lineages. The diagnostic approach to soft tissue tumours, including angiomyolipoma, requires optimal processing and sectioning of resected specimens. This paper is believed to be the first case of primary soft tissue angiomyolipoma reported in the veterinary literature.
