Abstract:
Granuloma annulare is a benign dermatosis of unknown etiology and chronic course, with different clinical variants. The disseminated form predominantly affects the extremities, sparing the trunk. We present the case of a 52-year-old woman with recurrent and autolimited outbreaks of disseminated granuloma annulare that began at summer time and involved the legs, arms and the dorsal area of hands. No pathological findings were observed in the laboratory studies performed. Histopathological examination confirmed our clinical suspicion. The development of granuloma annulare in photoexposed areas and sun exposure as a precipitating factor have been rarely reported in the literature.

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.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen.
