Tinea incognito in Italy: a 15-year survey
No full textTinea incognito or steroid modified tinea is a dermatophytic infection in which topical or systemic steroids, administered as a result of dermatological misdiagnosis or preexisting pathologies, have modified the clinical appearance of the fungal infection, transforming the typical ringworm and mimicking other skin diseases. This is a retrospective study of the agents, clinical aspects, sources of infection of 200 cases (98 males, 102 females, mean age 42 years) of tinea incognito, observed in Siena and Milan, Italy, in the period 1987-2002. In order of decreasing frequency, Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyton floccosum, Microsporum canis, Microsporum gypseum, Trichophyton violaceum and Trichophyton erinacei were isolated. The clinical appearance of the infection was lupus erythematosus discoid-like, eczema-like, rosacea-like, especially on the face, impetigo-like and eczema-like on trunk and limbs. Less often the dermatophytosis resembled psoriasis, purpura, seborrhoic dermatitis and lichen planus. There was folliculitis in 9% of cases and dermatophytid in 3% of cases. Antimycotic therapy brought about clinical and mycological recovery in all patients except one, who had iatrogenic immunodepressio
Retrospective study of mycotic infections of the feet due to dermatophytes and moulds in Siena from 1993 to 2002 [Infezioni micotiche dei piedi da dermatofiti e muffe a Siena. Studio retrospettivo dal 1993 al 2002]
No full textAim. The aim of this paper is to evaluate the occurrence of mycotic infections due to dermatophytes and moulds, diagnosed at the Mycology Unit of the Dermatology Department, Siena, the only unit in Siena Province offering mycological examination, from 1993 to 2002. Methods. Five hundred and thirthy-nine patients with suspected mycotic infection underwent mycological examination. Diagnosis was based on direct microscope observation and culture of pathological material on Sabouraud dextrose agar with CAF and cycloheximide and on Sabouraud dextrose agar with CAF only. Results. Dermatophyte infections were found in 190 cases (112 males, 78 females, age 5-71 years, mean age 38) and mould infections in 13 cases (9 males, 4 females, age 28-52 years, mean age 37). With regard to dermatophyte infections, Trichophyton rubrum was isolated in 71% of cases, Trichophyton mentagrophytes in 21% and Epidermophyton floccosum in 8%. The infections manifested as intertrigo in 87%, tinea pedis bullosa in 8%, "moccasin foot" in 4% and intertrigo plus bullae in 1%. With regard to mould infections, Fusarium was isolated in 11 cases (Fusarium oxysporum in 10 cases and Fusarium solani in 1). The clinical picture was interdigital intertrigo with areas of whitish, macerated and eroded skin. Scytalidium hyalinum was isolated in 2 cases. The clinical manifestations were "moccasin foot" in 1 case, plantar and interdigital desquamation in the other. Conclusion. Mycotic infections of the feet are usually caused by dermatophytes, rarely (7%) by moulds. The most frequent site is between toes IV and V. Predisposing factors are warm maceration, occlusion and, in mould infections, contact with soil. When mycotic infections of the feet are suspected, it is advisable to perform mycological examination with culture of pathological material not only on Sabouraud dextrose agar with CAF and cycloheximide but also on Sabouraud dextrose agar with CAF only. Long-standing monitoring of mould infections is necessary because they are dangerous in immunodepressed patients
A case of pityriasis versicolor atrophicans
No full textA case of pityriasis versicolor atrophicans caused by Malassezia globosa is reported in a 49-year-old woman. Diagnosis was based on direct microscopic examination and culture. Differential diagnosis was performed with respect to other skin diseases manifesting with cutaneous atrophy
Onychomycosis due to Ulocladium botrytis
No full textA case of disto-lateral onychomycosis of the third toe of the right foot of a 45-year-old man is reported. The agent of infection was Ulocladium botrytis, a mycete not hitherto reported to infect humans. The patient underwent mycological examination consisting of direct microscope observation and culture of pathological material. Diagnosis was based on the macro- and microscopic characteristics of the colonies. Fragments of the latter were also examined by scanning electron microscope. Clinical and mycological recovery was achieved after 3 months of topical therapy with ciclopiroxolamin

Contact dermatitis due to ciclopiroxolamine
No full textWe report a case of contact dermatitis because of ciclopiroxolamine milk in a 43-year-old woman with tinea pedis and onychomycosis caused by Trichophyton rubrum. Ciclopiroxolamine is regarded as a weak sensitiser because of the few allergic reactions described in relation to its widespread us
