Subcutaneous nodules of the scalp: preoperative management.

The differential diagnosis of subcutaneous lesions of the scalp is extensive and includes many tumors with intracranial and intraosseous extension. The vast majority of lesions seen by the dermatologist will be benign. However, certain lesional characteristics increase the likelihood of a serious disorder and these must be evaluated preoperatively. We review the important features of subcutaneous scalp lesions and suggest a systematic approach to diagnosis based on patient age, lesion morphology, location, and radiographic findings.

Unilateral facial telangiectasia macularis eruptiva perstans.

A 36-year-old man developed unilateral facial telangiectases over a 10-year period. Histopathologic examination showed collections of mast cells. This patient has an unusual variant of telangiectasia macularis eruptiva perstans. The differential diagnosis of facial telangiectases is discussed. Mastocytosis should be considered in patients presenting solely with telangiectases.

Cutaneous reaction to spironolactone resembling lupus erythematosus.

A cirrhotic male patient was admitted with a skin eruption. He had been taking spironolactone and hydrochlorothiazide for two months prior to admission. The morphology and distribution of skin lesions resembled that of systemic lupus erythematosus (SLE). Histologic changes in the skin biopsy specimen were consistent with SLE. Biopsy specimens of normal and affected skin were reported to show weak focal deposition of IgM and complement at the dermal-epidermal junction. However, there was a striking absence of serologic evidence of SLE. The rash disappeared when all medications were discontinued and reappeared when the patient was given spironolactone. The character and distribution of the rash after spironolactone administration was identical to the previous lesions. It disappeared again when spironolactone was withdrawn. This response to spironolactone is good evidence that it and not chlorothiazide was responsible for the rash. The latter drug has been reported to cause SLE-like skin changes.

Myocardial infarction in dermatomyositis.

A case of dermatomyositis manifesting electrocardiographic and vectorcardiographic changes compatible with an inferior and anterolateral wall myocardial infarction is presented herein. The nonocclusive nature of the heart muscle damage is evidenced by perfectly normal coronary artery angiography. We believe that this is the first reported case of a myocardial infarction pattern apparently due to dermatomyositis.

Lupus erythematosus exacerbated by griseofulvin.

Because griseofulvin is one of the safest systemic medications, its side effects are often forgotten. This paper serves as a reminder that griseofulvin can precipitate or exacerbate lupus erythematosus. Two patients are described: one had a photosensitivity reaction to griseofulvin which precipitated discoid LE skin lesions, without any previous evidence of LE. The other, who had known systemic LE, developed a systemic reaction, consisting of fever and malasise.

Poikiloderma vasculare atrophicans.

A 46-year-old Negro man with poikiloderma vasculare atrophicans is described. The disease progressed graduall.y for 22 years, with lesions appearing over the neck, trunk and extremities in an asymmetrical distribution, but it did not become lymphoma or collagen disease. Treatment did not appear to influence the course of the disease.

Fournier's gangrene of the scrotum.

Gangrene involving the male genitalia is extremely rare. It may occur without any predisposing cause. This necrotic process passes through various stages, and is self-limited. No radical surgical procedure is indicated. A case of typical Fournier's gangrene of the scrotum is presented.
