Tinea capitis mimicking folliculitis decalvans
Abstract:
We report on an adult patient with tinea capitis caused by Microsporum canis, who presented with diffuse alopecia and follicular pustules, mimicking folliculitis decalvans. Examination of the scalp showed severe alopecia with prominent involvement of the frontal and vertex scalp: the skin was markedly erythematous with pustules and brownish crusts. Videodermoscopy revealed visible follicular ostia, numerous pustular lesions and several comma hairs. Fluconazole 150 mg a week for 8 weeks associated with ketoconazole shampoo cleared the inflammatory lesions and produced complete hair regrowth.

The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
