Keratosis Follicularis. Presented by Dr. Maurice J. Costello.
F. A., a woman aged 51, has had an erythematous, crusted eruption of the face for 14 years. The lesions began as match-head-sized papules which crusted and by confluence presented the plaque-like lesions now seen. These originally covered the entire face, but there are now visible on the nose and nasolabial folds patches of normal skin. There are a few lentil-sized, brown, greasy, crusted papules on the outer third of the left clavicle. The diagnosis was confirmed by biopsy.
The patient has received vitamin A, 150,000 units daily, for the past 5 years. She states that the eruption always clears in the winter but recurs in the summer. The present eruption, which had its onset in November, is unusual for her.
Dr. Perry Sachs: I would suggest that a biopsy be performed on a palmar lesion to determine its exact nature.
