A clinical look at the aging skin.

The aging Caucasian skin becomes yellow, dry, wrinkled and inelastic. Deterioration increases its susceptibility to malignant neoplasms, pruritus, and candidal infection. In addition, psychosomatic problems vascular disease, "little strokes," and chronic malnutrition may precipitate or exacerbate skin disorders in the elderly. Treatment with "strong" medications should be taboo because of the fragility of senile skin. The risk of toxic reactions or of allergic sensitization is great. Because healing is retarded in old tissue, time is an indispensable component of successful treatment.

Adolescent

Tumor of the follicular infundibulum.

A histopathologically unique tumor originating from the infundibular portion of vellus hair follicles is presented and the clinical and microscopic features of such a case are described. A superficial subepidermal shelf of trichilemmal structure differentiates the lesion from the lobular acanthosis of trichilemmoma.

Basal cell nevus syndrome in a black patient: report of a case and review of the literature.

An 80-year-old black man had multiple basal cell epitheliomas (BCEs), palmar pits, and mandibular cysts. This patient is unusual, not only because of multiple BCEs, but also becuase they developed when the patient was at age 77. Only three other black patients with multiple BCEs in association with basal cell nevus syndrome have been reported previously.

Black or African American

Carcinoma of the inframammary crease.

Carcinoma of the inframammary crease is an uncommon but distinctive manifestation of carcinoma of the breast. This report of a case illustrates the clinical and histophathologic features. The patient's tumor was exophytic and fissured, and the initial biopsy specimen mimicked basal cell epithelioma.

Adenocarcinoma

Topical clindamycin in acne vulgaris. Safety and stability.

Eighteen patients with acne vulgaris used a hydroalcoholic solution of clindamycin hydrochloride topically. Serum samples were obtained and assayed for clindamycin; no evidence for systemic absorption was found. The clindamycin capsules used in this preparation contained insoluble fillers that may be removed by filtration without loss of in vitro antibacterial activity. This solution is stable for at least six months.

Acne Vulgaris

Lichen aureus.

A case of lichen aureus is described to record its clinical and histopathologic features. The disease is a variant of the pigmented purpuric eruptions, the common characteristic of which apparently resides in an abnormality of the minute cutaneous blood vessels.

Adult

Bullous transient acantholytic dermatosis.

We have been three cases of a bullous variant of transient acantholytic dermatosis. Skin biopsy specimens showed histopathologic changes identical to pemphigus foliaceus, but immunofluorescent studies showed no tissue-fixed or circulating antibodies to intercellular antigens. The bullous eruption lasted a few weeks to several months and healed without scarring or recurrence. The lesions healed with topical and/or systemic corticosteroid therapy.

Acantholysis

Maculopapular eruption in hypoparathyroidism.

A 12-year-old girl with idiopathic hypoparathyroidism manifested an erythematous, follicular, maculopapular eruption on her truck and arms. The eruption abated when the serum calcium rose to normal levels.

Child

Experimental study on healing of bone fractures using L-dopa.

Internal fixation with plate and screws was combined with administration of L-Dopa, which presumably operates by stimulating release of growth hormone. The combination induces osteogenesis, callus formation and complete union in the experimental femur osteotomy gap (10-20 mm long). Complete clinical and radiologic union was achieved in dogs treated for 3-6 weeks, thus achieving healing of a bone gap which otherwise would have formed a pseudarthrosis.
