TOENAIL BIOPSY: ONYCHOMYCOSIS, DIAGNOSTIC OF TRICHOPHYTON GENUS. ICD-9 #110.1
The presence of fungal hyphae in this specimen is consistent with Trichophyton Rubrum or Trichophyton Mentagrophytes. These latter are organisms commonly isolated from podiatric specimens. Nails infected with these organisms usually present as distal subungual infections. Toenails are frequently involved more than fingernails. These organisms also produce a chronic type of tinea pedis. Infections involving the interdigital areas can produce erythema, fissuring, and may extend into other portions of the foot. These organisms, because of their affinity for skin, can be susceptible to topical agents such as: Econazole, Oxiconazole, terbinafine, triacetin, and Undecylenic acid. Other agents have been approved by the FDA for oral therapy, including Itraconazole. Other causes of dystrophic or degenerative nail disorders include trauma, psoriasis, lichen planus, and eczema.
