Cutaneous horn (cornu cutaneum) is a clinical diagnosis referring to a conical projection above the surface of the skin that resembles a miniature horn. The base of the horn may be flat, nodular or crateriform. The horn is composed of compacted keratin. Various histologic lesions have been documented at the base of the keratin mound and histological confirmation is often necessary to rule out malignant changes. Tenderness at the base of the lesion and lesions of larger size favour malignancy. Malignancy is present in 16-20% of the cases with squamous cell carcinoma being the most common type. We report a young male patient with a keratin horn on the right index finger tip.
Fournier′s gangrene is a rare, fulminant, though generally localized disease of the scrotum and penis with occasional extension up the abdominal wall. The usual organism is an anaerobic streptococcus synergistic with some second organism. Our case was unusual in that only the penis was involved without involving the scrotum or abdominal wall. Early therapy is the key, including hospitalization, debridement of entire shaft of the penis distal to the devasted area without excising the normal skin, parenteral broad-spectrum antibiotics & skin grafting. Only few cases of Fournier′s gangrene of the penis have been reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
