Solitary epithelioid histiocytoma (reticulohistiocytoma) of the glans penis.

Solitary epithelioid histiocytoma (previously called reticulohistiocytoma) is a rare benign dermal histiocytic proliferation characterized by the presence of large, eosinophilic histiocytes with 'glassy' cytoplasm. This entity assumes importance because of its close histologic resemblance to several benign as well as malignant cutaneous lesions. Involvement of the penis is extremely rare, and to our knowledge, only one case has been previously described in the literature.

Mixed adenocarcinoma-carcinoid (collision tumor) of the appendix.

Foreign body reaction to soft tissue filler simulating atypical lipomatous tumor: report of a case.

Injectable silicone or microimplant has been extensively used for the soft tissue augmentation. Here we report a case of cystic granulomatous reaction to injectable tissue filler, possibly liquid silicone, used for tissue augmentation in the buttocks. Patient presented with a progressive painful swelling in the lower back over L4-L5 and S1 lumbosacral region of 4-month duration.

Acute amebic appendicitis: report of a rare case.

Acute appendicitis of amebic origin is considered a rare cause of acute appendicitis. We report a case of amebic appendicitis presenting with fever, severe pain in the right lower quadrant of the abdomen and rebound tenderness. Lab investigations revealed neutrophilic leukocytosis.

Jejunal perforation caused by schistosomiasis.

We report an extremely unusual case of jejunal perforation caused by adult schistosoma worm in a 49-year-old South Korean man who presented with acute abdomen. To our knowledge, this is the first case of jejunal perforation associated with adult worm of schistosoma.

An unusual case of extensive epididymotesticular malakoplakia in a diabetic patient.

A 67-year-old Saudi man with poorly controlled diabetes-mellitus underwent orchiectomy for a painful left testicular swelling that did not respond to antibiotics. Clinical diagnosis was testicular malignancy. Histologic workup demonstrated extensive involvement of the testis and epididymis by diffuse infiltrate of large histiocytes with eosinophilic granular cytoplasm and numerous Michaelis-Gutmann bodies, which were diagnostic of malakoplakia.

Paraganglioma of cauda equina: report of seven cases.

The authors report seven uncommon cases of paraganglioma of the cauda equina region with reference to their clinical, radiological, and pathological findings. The common presenting symptoms in all the patients were low backache with radiation to both thighs, sensory and motor deficits in four patients, and urinary retention in three patients. One patient presented with ataxia and superficial sidrosis of the brain.
