A perplexing case of superficial granulomatous pyoderma with sporotrichoid-like distribution.

Superficial granulomatous pyoderma (SGP) is a rare pyoderma gangrenosum (PG) variant that differs from classic PG in that the ulcers tend to be more superficial, lack a rapidly advancing border, and are not typically associated with an underlying systemic disease. The ulcers are most commonly painless and located on the trunk, with a clean granulating base. They generally do not show undermining but may have a vegetative border.

Tinea capitis: A single-institution retrospective review from 2010 to 2015.

Background/objective: Tinea capitis is a common infection of scalp hair in children. The prevalent etiologic organism has changed significantly over time, which may reflect the complex interaction of environmental factors, genetic predisposition, and movement of populations. We evaluate the prevalence of different infectious organisms causing tinea capitis and describe the clinical characteristics.
