| Diagnosis: | ONYCHOMYCOSIS | Category: | infections and infestations | ||
| Body Site: | nail, foot | Age: | 48 years | ||
| Contributor: | Greg Hosler, MD, PhD | ||||
| Description: | Histologic sections are of nail plate. Focal serm collects on the undersurface of the nail. Organisms are difficult to appreciate at this power. | ||||
| Comments: | Onychomycosis is a very common condition, often caused by dermatophyes. In this particular case, the organisms are budding yeast forms, most consistent with Candida spp. There is some histologic overlap between these and the spores of dermatophytes, but the presence of budding and a more dark purple color allows distinction. Additionally, there are no hyphal structures. Candida is a common cause of paronychia and may colonize the nail plate. | ||||

She was treated successfully with oral terbinafine 250 mg tablet daily for 3 months. Tinea Unguium (Onychomycosis) is mycotic infection of the nail unit. The term tinea unguium is used to describe infection by dermatophytes; the term onychomycosis is nonspecific and refers to nondermatophytes and dermatophytes infections of the nail unit. Tinea unguium is generally caused by members in the genera Trichophyton and Epidermophyton and is most common in adults. T. Rubrum causes the majority of infection. | ||||
