Yellow papules and nodules in an infant

Benign cephalic histiocytosis with extra‐facial manifestations

“…The differential diagnosis is mainly with JXG and GEH, but also with cutaneous mastocytosis, plane warts and lichenoid sarcoidosis (Table 1). 3,6 BCH, JXG and GEH exhibit a similar dermoscopic pattern, although in our cases the background colour was browner than orange. Clinical manifestation can also help differentiate BCH from other non‐LCH.…”

“…Histopathologic examination reveals a mononuclear infiltrate with foamy histiocytes and some Touton cells are observed 3. 6 GEH is more common in adults and is characterised by a rapid onset and wider distribution of lesions with occasional mucosal involvement. Histologically, GEH may be similar to BCH.…”

“…Histologically, GEH may be similar to BCH. 6 Dermoscopy helps to easily differentiate BCH from plane warts, which present small red dots regularly distributed on a light brown to yellow background. 7 The histological appearance and immunochemistry are very useful for making diagnostic differentiation between cutaneous mastocytosis and lichenoid sarcoidosis.…”

“…JXG usually presents disseminated nodular lesions, sometimes associated with ocular involvement. Histopathologic examination reveals a mononuclear infiltrate with foamy histiocytes and some Touton cells are observed 3 6 . GEH is more common in adults and is characterised by a rapid onset and wider distribution of lesions with occasional mucosal involvement.…”
