Primary dural follicular lymphoma masquerading as meningioma: a case report.

Patient presented with a dural-based mass lesion and was diagnosed as having meningioma on imaging. Post-resection histological examination revealed a low grade follicular lymphoma. The patient received cranial radiotherapy and is recurrence-free at 6-month follow-up. Primary dural follicular lymphoma is an exceedingly rare entity with only as few as six reported cases. Herein, the clinico-radio-pathological appearances and treatment protocol of this entity are discussed.

Syringocystadenocarcinoma papilliferum at unusual site: inherent lesional histologic polymorphism is the pathognomon

Syringocystadenocarcinoma papilliferum is an extremely rare cutaneous adnexal carcinoma, considered by the WHO as the malignant form of syringocystadenoma papilliferum (SCAP).1 The rarity of this tumour has been referred to, in a recent paper2 which reviews the entity and lists a total of 12 reported cases till 2010, since it was first described in 1980.3 Eight of these 12 cases were reported to have occurred in the head and neck region (six on the scalp, one …

However, as highlighted by Ananthakrishnan in 1993, two decades down the line, still scenario remains same, and it may be difficult to consider for summative assessment of universities. However, keeping this in mind the tremendous advantages of OSPE at least it should be considered for formative assessment if not for summative assessment.[5]

Significance of perineural invasion in locally advanced bucco alveolar complex carcinomas treated with surgery and postoperative radiation ± concurrent chemotherapy

The purpose of this study was to evaluate prognostic factors, locoregional control, and survival in locally advanced bucco‐alveolar complex cancers.

Primary retroperitoneal mucinous cystadenocarcinoma in a male patient

Primary retroperitoneal mucinous neoplasms are extremely rare tumors. Less than sixty cases have been reported in international literature until date, with striking female predominance. We report a case of primary mucinous cystadenocarcinoma of the retroperitoneum in a 51-year-old male presenting with nonspecific abdominal complaints. This case is being highlighted for its rare occurrence in a male patient.

Round cell epithelioid GIST (gastrointestinal stromal tumour) in an endoscopic biopsy is a diagnostic confounder.

The authors present a case of a 53-year-old lady, with vague upper gastrointestinal symptoms and progressive iron deficiency anaemia, stool positive for occult blood and progressive weight loss. Endoscopically a lumenally protruding mass, with extensive mucosal ulceration was seen. Carcinoma, stromal tumour and lymphoma were the clinical differential diagnoses. Histologic sections showed a dense, diffuse and adhesive mucosal infiltrate of round cells. The tumour cells were round, with high nuclear – cytoplasmic ratios, without any specific cyto-architectural attribute except rare subtle plasmacytoid aspect (figures 1 and 2A,B). A non-Hodgkin lymphoma and poorly differentiated adenocarcinoma were initially considered, and immunochemistry requisitioned. The initial sets of immunomarkers showed the infiltrating cells …

Bizarre endothelial reaction: histological mimicry of epithelial malignancy in gastric endoscopic biopsy.

Gastric endoscopic biopsies often reveal pseudoneoplastic processes which can be misinterpreted as malignant by the unwary.1 2 In this case the lamina propria of the non-ulcerated gastric mucosa was densely infiltrated by epithelioid cells with …
