1/7. pityriasis rotunda mimicking tinea cruris/corporis and erythrasma in an Indian patient.

    pityriasis rotunda is a rare disease characterized by perfectly round to oval, sharply defined, scaly, hypo/hyperpigmented patches of variable number and size located mainly over the trunk and proximal extremities. More than 95% of the reported cases in medical literature are from three countries/ethnic populations, namely japan, south africa (Bantu), and italy (Sardinian islanders). To the best of my knowledge, no patient with the characteristic clinico-pathologic features has been reported from the Indian subcontinent. I report a 44-year-old man with eighteen pityriasis rotunda patches, persistent for nearly 20 years. The lesions in the groin and axillae closely resembled erythrasma and tinea, and he had received treatment for these conditions several times in the past. Histopathology of the skin biopsy showed thinning of the epidermis with a thinned-out granular layer and a sparse lymphomononuclear infiltrate in the dermis. A review of literature suggests that there are two subsets of the disease. The type I subset is comprised of pityriasis rotunda associated with systemic illness and is seen in Black or Oriental patients with no family history of the disease. The lesions tend to subside on treatment of the underlying illness. The type II subset patients are Caucasians as well as Blacks and Orientals with no underlying systemic illness. Familial occurrence is possible; lesions tend to be persistent and unresponsive to therapy. ( info)

2/7. Case report. Erythrasmoid pityriasis versicolor.

    A 50-year-old Caucasian man with pityriasis versicolor that was localized almost exclusively in the inguinal folds and was characterized by lesions clinically superimposable on those of erythrasma is described. Due to these clinical characteristics, it is proposed that this variety of pityriasis versicolor is defined as 'erythrasmoid'. ( info)

3/7. pityriasis versicolor on the groin mimicking erythrasma.

    pityriasis versicolor (PV) is a widespread dermatomycosis caused by yeasts. erythrasma is a superficial bacterial skin disease affecting the major folds of the body, particularly the groin. We report the case of a 45-year-old man, affected by PV, exclusively localized in the inguinal folds and in the inner surface of the thighs, characterized by lesions clinically reproducing erythrasma. The authors underline the possibility that PV mimics erythrasma and vice versa, especially in those countries in which both diseases are quite common, and stress the importance of performing a simple mycological examination to avoid gross diagnostic and therapeutic errors.

4/7. Coexistence of pityriasis versicolor and erythrasma.

    We describe a 53-year-old woman with pityriasis versicolor together with erythrasma that was localized in the axillary and genitocrural region. The coexistence of these infections is rare and we propose the use of methylene blue stain for the diagnosis of both diseases. ( info)

5/7. corynebacterium minutissimum infection.

    Two cases of infection due to corynebacterium minutissimum are described. On the basis of biochemical tests the organisms were thought at first to be corynebacterium jeikeium. methods of distinguishing between these species and the role of C. minutissimum in the pathogenesis of erythrasma and other skin infections are discussed.

6/7. Disciform erythrasma.

    A case of disciform erythrasma is presented. This unusual manifestation of a common cutaneous infection may mimic other dermatologic disorders, including lichen sclerosus et atrophicus and plaque-type parapsoriasis. The condition is characterized by an atrophic appearing surface, located in nonintertriginous areas. Appropriate diagnostic procedures easily differentiate disciform erythrasma. These include wood's light examination, potassium hydroxide preparation, and skin scrapings or tissue sections stained with Gram stain, periodic acid-Schiff, Giemsa, or methylene blue. ( info)

7/7. Nonfluorescent erythrasma of the vulva.

    BACKGROUND: erythrasma is an uncommon vulvar infection, best diagnosed by its fluorescence under the wood lamp. This report shows that despite a negative wood lamp examination, the diagnosis can be made histologically. CASE: A 42-year-old woman was referred to our clinic with a persistent candidal infection. Evaluation included a wood lamp examination, wet mount, and potassium hydroxide test of the affected skin, all of which were negative. A biopsy of the area demonstrated rods and filamentous organisms in the keratotic layer consistent with a corynebacterium minutissimum infection. The patient was diagnosed as having erythrasma, and she responded to oral erythromycin. CONCLUSION: Persistent vulvar diseases may be caused by erythrasma despite a negative wood lamp examination. The diagnosis can be made by biopsy of the lesion. ( info)
