Subungual glomus tumor: surgical and histopathologic evaluation.

Glomus tumor is a rare and benign vascular tumor, arising from neuromyoarterial glomus bodies. It is generally localized on the hand and especially the nail bed and is usually solitary. Pain, tenderness, and temperature sensitivity are the classic triad of symptoms of a glomus tumor.

White fibrous papulosis of the neck.

A 56-year-old white man with multiple, discrete nonfollicular papules on the neck is presented. Clinical and histopathologic features were compatible with the entity of white fibrous papulosis of the neck (WFPN). Pseudoxanthoma elasticum-like papillary dermal elastolysis (PXE-PDE) and WFPN are further clinicopathologic patterns of intrinsic aging.

Dermatofibroma on the palmar surface of the hand.

Case 1: A 58-year-old man presented with a solitary asymptomatic nodule on his thumb (Figure A). After trauma with a rusty nail approximately 20 years ago, he had developed a small papule, which had enlarged gradually for a few days initially before stabilizing. His personal and family medical histories were unremarkable.

Porokeratosis of Mibelli induced by topical corticosteroid.

Background: [corrected] Prorokeratosis of Mibelli is a chronic disorder characterised by slightly atrophic plaques surrounded by keratotic border.

Methods And Results: A 45-year-old with clobetazole propionate ointment for psoriasis over 15 years developed characteristic lesions of porokeratosis Mibelli on the elbows. Histopathological examination revealed the cornoid lamellae located on the edges of the specimen and psoriasiform acanthosis and a spongiotic pustule formation in the center of the specimen; thus, it was suggested as 'psoriasis encircled by porokeratosis'.

Effect of BCG vaccine on peritoneal endometriotic implants in a rat model of endometriosis.

Objective: To investigate the effect of Bacillus Calmette-Guerin (BCG) vaccine on peritoneal implantation of endometrial tissue in rats.

Methods: Forty sexually mature virgin Wistar albino rats weighing 190-200 g were randomly assigned (double blind) to two groups. The rats in the first group were vaccinated with 0.

ITP as an initial manifestation of subacute cutaneous lupus erythematosus.

Subacute cutaneous lupus erythematosus (SCLE) is an entity characterized by widespread polycyclic lesions that heal without scarring. Skin lesions with marked ultraviolet sensitivity are distributed in an annular and/or psoriasiform configuration. Idiopathic thrombocytopenic purpura, which is an autoimmune disease (ITP), is mediated by a destructive immunoglobulin G antibody response to the platelets' membrane components.

Psoriasiform contact dermatitis due to propolis in a beekeeper.

Background: More than 250 cases of allergic contact dermatitis due to propolis have been described. A few of these occurred in beekeepers.

Objective: To describe a case of psoriasiform dermatitis caused by propolis in a beekeeper who thought that his lesions were related to honeybee stings.
