Trichomycosis axillaris is a common but underdiagnosed condition of the skin. The dermoscopic image of this disease is not previously described in the scientific literature. We believe that dermoscopy is a convenient and interesting diagnostic method that may aid in the diagnosis. Read More
Trichomycosis axillaris is a common tropical disease usually affecting the hair shafts of the axillae, characterized by nodular concretions along the hair shafts caused by Corynebacterium tenuis. We describe a 38-year-old patient with trichomycosis axillaris. Treatment, which included shaving of affected hair, followed by topical 3% erythromycin cream and clotrimazole powder was fully effective. Read More
Skin infections are common and may be caused by bacteria, fungi or viruses. Breaks in the skin integrity, particularly those that inoculate pathogens into the dermis, frequently cause or exacerbate skin infections. Bacterial skin infections caused by corynebacteria include erythrasma, trichomycosis axillaris and pitted keratolysis. Read More
Between June 1988 and December 1990, 1018 cases of superficial mycoses were investigated. Diagnosis was confirmed by microscopic examination in 503 cases and the causal agent was isolated in 490 cases. Tinea capitis accounted for 47. Read More
Trichomycosis axillaris is a trivial disease of worldwide occurrence that is believed to be caused by the genus Corynebacteria. In addition to invading the cuticle of the hair, the Corynebacteria are believed to elaborate a material that, together with colonies of bacteria, make up the concretions formed on the hair shaft. A careful review of the literature on this disease indicates that this latter belief may not be correct. Read More
Study of a case of trichomycosis axillaris by electron microscopy revealed a specific encapsulated Corynebacterium adhering to but not penetrating the hair shaft. External to this were two other biochemically distinctive pleomorphic Corynebacteria shown to be incapable of direct adherence to the hair. All three types were entrapped in a virtually insoluble cement substance, which they elaborate and which is responsible for the grossly visible colonization that is so characteristic of this disease.

Acquired hair shaft abnormalities resembling genetic trichorrhexis nodosa were seen in two patients. Selenium shampoo and bacterial infection with trichomycosis axillaris may have been the contributing factors. There is a possibility that strongyloides larvae caused trichonodosis in one patient.

Trichomycosis is a bacterial infection of hair that involves the axilla and, uncommonly, the pubis. The causative agent of trichomycosis pubis is probably the same as that in trichomycosis axillaris, as determined by culture and electron microscopy. We believe that increased awareness of trichomycosis pubis will show it to be common in certain environments. Read More
