“…Evidence of tissue damage or microtrauma, most probably resulting from solar irradia tion, is denoted by the course followed by the sanguinolent exudate through the epithelium [18], Moreover, the detection of the 'splinter hemorrhage' and the subungual hemorrhages [19] suggest an increased susceptibility of the injured tissue to mechanical microtraumas.…”

Two patients, whom we had under surveillance since 1969, were found to develop photo-onycholysis from orally administered 8-methoxypsoralen and sunlight irradiation. Morphological examination of the nail bed revealed characteristics of a microtrauma. The photosensitizing effect of the drug induced the generation of numerous binucleate, tetranucleate and multinucleate epithelial cells as well as numerous binucleate and tetranucleate fibroblasts in the dermis.

“…The dermis of the nail bed contains both capillaries and glomus bodies, arranged along the longitudinal folds. It is this arrangement that gives splinter hemorrhages their characteristic appearance 12,14 . A connective tissue network radiates vertically from the phalangeal periosteum to firmly attach the epidermis 10 .…”

Dermatologists and dermatologic surgeons are frequently presented with significant pathology of the hand. Because the hand plays such a unique and important role in man's everyday life, preservation and restoration of its form and function is critical. The hand is both powerful and extremely delicate. Before performing any procedures in this area, dermatologists and dermatologic surgeons must have a clear understanding of the cutaneous and deep anatomy of the hand and digits, as well as a thorough knowledge of the disease process being treated and the modality being used. This article reviews the intricate anatomy, the proper hemostasis and anesthesia, and many of the complications seen in dermatologic surgery and procedures of the hand, digits, and nails. With appropriate preoperative evaluation and precautions, many dermatologic procedures may be safely performed on the hand.

“…The rich vasculature from the palmar or plantar digital arteries and the glomus bodies found in the mesenchyme accounts for the pink color (Figure 3) (dusky red from hemosiderin in the cadaver) visible through the nail plate. When one of these vessels ruptures, the blood extravasates into these longitudinal ridges and is reflected through the plate as splinter hemorrhages 32 . It is of interest to note that the nail bed does not contain subcutaneous fat 3…”

A gross anatomic exploration of the nail unit was performed. The characteristic gross components of the nail unit and its relationship to the digital anatomy are described and presented in detail. Each segment of the nail unit is illustrated both photographically and with artistic illustration. It is our intention that through a simple gross dissection the nail structural unit may be better understood.
