ABSTRACT
Lipomembranous changes are distinctive histopathological findings, which include the presence of cystic cavities lined by crenulated, hyaline membranes in adipose tissue. It is likely that ischaemia is fundamental to the development of these lesions, and that lipomembranes are formed from the products of degenerating fat cell membranes by some unknown mechanism. Such changes may be seen, although rarely, in many types of subcutaneous inflammatory processes. However, an association with systemic lupus erythematosus (SLE) is rare. We report a patient with SLE who had the histological features of lipomembranous changes associated with vasculopathy.

Eccrine angiomatous hamartoma (EAH) is a benign hamartomatous tumour characterized by a combination of proliferative eccrine and vascular elements. Papillary haemangioma (PH) is a distinct cutaneous haemangioma with predominantly intravascular capillary proliferation within dilated thin-walled blood vessels. EAHs have been reported in combination with various vascular components. We present the first case in the dermatological literature, to our knowledge, of a patient with congenital EAH with the histopathological features of a PH.
