Acquired reactive perforating collagenosis should be considered when ulcera with oystershell-like keratotic plugs are found especially in patients with predisposing diseases like diabetes and renal insufficiency. A good interdisciplinary cooperation between internist and dermatologist is crucial for the early recognition by histopathology and the immediate treatment.
Symptomatic cardiac melanoma metastases are very rare. A 76-year-old woman was admitted because of dyspnea and intrathoracic pain 8 years after surgery of a superficial spreading melanoma and 4 years after resection of in-transit metastases. MRI and echocardiography disclosed an intracavitary right atrial mass. Histologically a cardiac melanoma metastasis was found. Unspecific cardiac symptoms in a patient with elevated risk for distant metastases of melanoma should be further investigated to discover cardiac metastasis early.
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.
