Subcutaneous Fat Necrosis of the New-Born

An Unusual Case of Subcutaneous Fat Necrosis in a Newly Born Infant

“…By way of contrast the case resembled others previously recorded in the onset of abnormal signs within three weeks of life (Papadia and Fransvea, 1958;Fox, 1933;Hering and Undeutsch, 1956;McIntosh et al, 1938), followed by disappearance within a few months (Papadia and Fransvea, 1958;Hering and Undeutsch, 1956;Wesener, 1957); birth at or after term with an average or above average birth weight (Papadia and Fransvea, 1958;Fox, 1933); normal haematological and biochemical findings (Papadia and Fransvea, 1958;Hering and Undeutsch, 1956); and a tendency for the necrotic lesions to be distributed symmetrically (Fox, 1933).…”

“…The sites of the lesions differed from those most commonly involved (Papadia and Fransvea, 1958;Hering and Undeutsch, 1956;Wesener, 1957;Fox, 1933). There was no local tenderness or plaque-like induration (Papadia and Fransvea, 1958;Fox, 1933;Wesener, 1957).…”

“…Possibilities were considered with dermatological and surgical colleagues, and diagnoses tentatively suggested, only to be discarded, included surgical emphysema, lymphangioma, reticulosis, and neurofibromatosis. The fact that fat necrosis was not seriously considered is explained by the absence of attachment of the skin to the underlying lesions (Fox, 1933;Papadia and Fransvea, 1958;Hering and Undeutsch, 1956), and of discoloration of the skin in the neighbourhood of the lesions (Papadia and Fransvea, 1958;Hering and Undeutsch, 1956). The sites of the lesions differed from those most commonly involved (Papadia and Fransvea, 1958;Hering and Undeutsch, 1956;Wesener, 1957;Fox, 1933).…”

Adiponecrosis E Frigore.

“…Histological examination shows small areas of necrosis in the adipose tissue, accompanied by a considerable cellular infiltration and sometimes haemorrhage. For details the reader is referred to text-books of dermatology and pediatrics, and to a paper by Howard Fox (1933), where an excellent description is given together with an extensive bibliography.…”
