Manifestations and etiology of cutaneous findings in cases of morbid obesity.

Morbid obesity is associated with a wide range of metabolic, infective, and organic disorders related to adipose tissue overload. While careful documentation of internal autopsy findings is usual, skin manifestations may be overlooked. Skin manifestations are quite diverse and include striae distensae, skin tags, plantar hyperkeratosis, acanthosis nigricans, the sequelae of hyperandrogenism, lymphedema, panniculus morbidus, chronic venous insufficiency, stasis dermatitis, leg ulceration, intertrigo, cellulitis, pressure ulcers and 'buried penis'. Obesity has also been associated with hidradenitis suppurativa, psoriasis, atopic dermatitis, melanoma, systemic lupus erythematosus, lichen planus and acne vulgaris. Evaluating these findings at the time of autopsy may give a more complete assessment of a particular case and may also identify conditions that may have contributed to, or caused, death.
