Summary: A case of giant cell granuloma caused by Trichophyton rubrum is reported. Clinically the fungus had elicited skin coloured flat topped papules and plaques. Fungal filaments were absent in these areas histologically though skin scales revealed mycelia in KOH mount and grew T. rubrum. The histological findings suggest that histiocytes and plasma cells were mainly involved in the defence against T. rubrum infection in this case. Dermatophytoses are common in India. Tinea corporis is the second common mycosis in Madras, the first being tinea cruris, and the frequent sites affected are the waist and other areas of the trunk, both in children and adults. The usual type of skin lesions are rings and circinate patches with well defined border. In the present communication we have deseribed an atypical clinical and histological presentation by T. rubrum. Zusammenfassung: Bericht über einen Fall eines Riesenzellgranuloms bei oberflächlicher Trichophyton‐rubrum‐Infektion. Klinisch hatte der Pilz hautfarbene flache Papeln und Plaques hervorgerufen. Während histologisch Pilzelemente nicht nachgewiesen werden konnten, fanden sich im Nativpräparat Mycelien und in der Kultur Trichophyton‐rubrum‐Kolonien. Der histologische Befund deutet an, daß bei diesem Fall in erster Linie Histiozyten und Plasmazellen die Abwehr gegen die Trichophyton‐rubrum‐Infektion übernommen hatten.
