Pigmentary incontinence in fixed drug eruptions. Histologic and electron microscopic findings.

Pigmentary incontinence is a phenomenon observed in some inflammatory skin disorders. Clinically it may be seen as a slate-colored pigmentation. Histologically it is seen as an accumulation of melanin in the upper dermis. The possible mechanism for development of pigmentary incontinence is discussed based on a review of the literature and electron microscopic studies of fixed drug eruption.

Hermansky-Pudlak syndrome: albinism with lipofuscin storage.

The Hermansky-Pudlak Syndrome, a "tyrosinase positive' form of oculocutaneous albinism, is a triad comprising albinism, a hemorrhagic diathesis and ceroid-lipofuscin storage. A pedigree is presented showing consanguinity with a pattern of pseudodominance. Electroretinography in two isolated Hermansky-Pudlak subjects was distinctly abnormal, showing decreased rod and cone responses (as well as abnormal flicker fusion responses) in one patient, and reduced photopic and scotopic responses in another. The decreased ERG responses are discussed with reference to the known retinal abnormalities in both generalized oculocutaneous albinism and Batten's disease, another ceroid-lipofuscin storage disorder.
