Abstract:
Granulomatous mycosis fungoides (MF) is a rare subtype of MF, characterized by the histological presence of a granulomatous reaction, but distinct clinical characteristics are not present. A 41-year-old healthy man presented with poikiloderma, ichthyosis and erythematous scaly plaque. Histological examination of a biopsy taken from poikilodermic skin showed a granulomatous reaction to epidermotropic atypical lymphocytes. However, in other areas there were only findings of conventional MF without granuloma. Granulomatous MF may be associated with poikiloderma.

Papillary Dermis
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.
