Multiple pyogenic granuloma-like lesions following hair transplantation.
Multiple pyogenic granuloma-like lesions occurring at punch graft sites are an unusual complication of hair transplantation heretofore unreported. While the etiology and pathogenesis of such lesions remain elusive, physicians performing hair transplantations should be aware of this potential sequela.

Acanthosis nigricans-like hyperpigmentation secondary to triazinate therapy.
Cutaneous hyperpigmentation resembling acanthosis nigricans developed in two patients with malignant brain tumors following chemotherapy with triazinate (Baker's Antifol), a folic acid antagonist. In both cases, the eruption resolved after the cessation of drug administration and reappeared after the reinstitution of triazinate therapy. A skin biopsy specimen from one patient showed microscopic changes consistent with those found in acanthosis nigricans. The other patient had a decreased serum folate level that returned to normal as the hyperpigmentation resolved. Folate may have a role in triazinate-induced acanthosislike hyperpigmentation.
