causing recurrent superficial skin infections in an immunosuppressed patient.

is a gram-negative bacterium found commonly in water and soil. Initially thought to be non-pathogenic, it is now recognised as an important cause of nosocomial and opportunistic infections. Skin infections are rare, but cases of causing ulcers, abscesses and necrotizing fasciitis have been reported.

Poikilodermatous plaque-like hemangioma: Case series of a newly defined entity.

Background: We present a distinctive type of acquired vascular proliferation, for which we propose the name of poikilodermatous plaque-like hemangioma.

Objective: The aim of this study was to summarize the clinical and histopathologic features in a case series of poikilodermatous plaque-like hemangioma.

Methods: Sixteen cases were identified from the routine clinical and referral practices of the authors.

p63 and smooth muscle actin expression in low-grade spiradenocarcinomas in a case of CYLD cutaneous syndrome.

Low-grade spiradenocarcinoma is a rare skin tumor, with fewer than six reported cases, arising in the context of CYLD cutaneous syndrome (CCS; syn: Brooke-Spiegler syndrome [BSS]). We report two independent cases of spiradenocarcinoma arising in a 50-year-old man with CCS. The tumors grew rapidly, prompting clinical excision.

Melanocytic naevi with perineurial differentiation: a distinctive variant of neurotised naevi and a diagnostic pitfall with desmoplastic melanoma.

Aims: Spindle cell differentiation is not an uncommon finding in common acquired naevi, and may represent a form of neurotisation with Schwannian differentiation of melanocytes. Perineurial differentiation in this context appears to be very rare, and is only poorly documented in the literature. We therefore aimed to study this rare form of neurotisation in melanocytic naevi more comprehensively.

Ruptured spleen following laparoscopic cholecystectomy.

Background: Laparoscopic cholecystectomy is generally a safe and well-accepted procedure. However, in a small percentage of patients, it is associated with complications, such as bleeding and injury to the bile duct and other viscera. Splenic injury as a result of laparoscopic surgery has been reported only in the context of direct trauma, for example due to retraction in hand-assisted urologic surgery.
