Describe the symptoms of ringworm of the bearded region.
Ringworm of the bearded region (tinea trichophytina barbæ, tinea sycosis, parasitic sycosis, barber's itch) begins usually in the same manner as ringworm on other parts, as one or more rounded, slightly scaly, hyperæmic patches. In rare instances the disease may persist as such, with very little tendency to involve the hairs and follicles; but, as a rule, the hairy structures are soon invaded, many of the hairs breaking off, and many falling out. From involvement of the follicles, more or less subcutaneous swelling ensues, the parts assuming a distinctly lumpy and nodular condition. The skin is usually considerably reddened, often having a glossy appearance, and studded with few or numerous pustules. The nodules tend, ordinarily, to break down and discharge, at one or more of the follicular openings, a glairy, glutinous, purulent material, which may dry to thick, adherent crusts.

Ringworm Fungus (Microsporon) x 500. (After Duhring.)
Short, broken-off hair of scalp invaded with masses of free spores.
The disease may be limited to one patch, or a large area, even to the extent of the whole bearded region, becomes involved. The upper lip is rarely invaded. Ringworm of the bearded region is due to the trichophyton.
