Ulcerating paraffinoma.

One case of an ulcerating paraffinoma of the male mammary gland and another of the penis are reported. The former is the third and the latter the eighth of its kind described in the literature. Psychopathological features were associated with both cases, and additionally impotence with the latter. The treatment of paraffinomas is surgical. Subcutaneous mastectomy was performed on the mammary gland, leaving a high proportion of the affected skin in situ. Recovery was slow and the cosmetic end result not satisfactory. Re-injection of paraffin later required total excision of the entire anterior thoracic skin and subcutaneous tissues and skin grafting. The penile paraffinoma was treated by complete excision and again subsequent skin grafting. Both the functional and cosmetic results of the latter were good.
