Dermatophyte infections mimicking other skin diseases: a 154-person case survey of tinea atypica in the district of Cagliari (Italy).

Background: Although usually simple, the diagnosis of dermatophyte infection is sometimes neglected. An observational study has been realized to evaluate the role of corticosteroid exposure (tinea incognito) and of other primary characteristics of the dermatophytosis that from onset mimic other diseases and mislead an unexperienced physician.

Materials And Methods: Between 1990 and 2009, all cases of atypical dermatophytosis mimicking other skin diseases were collected from the more general number of dermatophyte infections diagnosed at the Dermatology Department of Cagliari University, Italy.

Dermatophytoses are frequent in children, but involvement of the facial skin has peculiar aspects that should be considered a separate entity: tinea faciei. Microsporum canis infection in tinea faciei has not been widely documented. To review cases of tinea faciei due to M.

Two cases of primary endonasal leishmaniasis in Sardinia (Italy).

Leishmaniasis is an endemic protozoan infection in Sardinia, one of the major islands of the Mediterranean Basin. We report two cases of endonasal primary Leishmaniasis, which is a very rare event in adult men who are immunocompetent, born in, and residents of Sardinia. The diagnosis was confirmed by the presence of intra and extracellular Leishmania amastigotes in the histological smear.

A 20-year survey of tinea faciei.

Tinea faciei is an uncommon dermatophytosis affecting the glabrous skin of the face. Between 1988 and 2007 at the Dermatology Department of Cagliari University, 107 cases of tinea faciei have been diagnosed, involving 72 females and 35 males, aged 2-72 years.

Primary cutaneous cryptococcosis in an immunocompetent host.

We report a case of primary cutaneous cryptococcosis in an immunocompetent host. Several nodules, isolated or sometimes joint to form plaques, affected the right arm. The arm was paralytic and hypoplastic, and a history of numerous abrasions picking firewood up preceded the onset of the eruption.

Adverse cutaneous reactions to selective cyclooxygenase 2 inhibitors: experience of an Italian drug-surveillance center.

Background: Selective cyclooxygenase (COX) 2 nonsteroidal anti-inflammatory drugs (NSAIDs) have been associated with a general lower incidence of side effects compared with nonselective NSAIDs. Postmarketing information has highlighted the need to reassess the risk evaluation for specific organs, including the skin.

Objective: A prospective databank to record all cases of adverse cutaneous reactions associated with the use of COX inhibitors was conducted at the Centre for Drug Surveillance of the Dermatology Department of Cagliari University.

Nail pigmentation caused by hydroxyurea: report of 9 cases.

We report a series of 9 patients, 6 men and 3 women, who presented nail hyperpigmentation arising between 6 and 24 months from the start of hydroxyurea therapy. The most commonly observed clinical pattern was that of longitudinal melanonychia. In only 1 patient, who was affected in all 20 nails, we observed longitudinal melanonychia, diffuse melanonychia, and hyperpigmentation of the skin.
