Perineurioma‐like EMA‐positive calvarial neoplasms: clinicopathological study of eight cases

Histopathology, Volume 89, Issue 3, Page 544-553, September 2026.
Perineurioma‐like, EMA‐positive calvarial neoplasms (PLECN) are a rare group of intraosseous spindle cell tumours that demonstrate overlapping morphologic features of perineurioma and fibroblastic meningioma. These lesions tend to behave indolently but show a propensity for progressive growth.

Langerhans Cell Histiocytosis in a Newborn

Journal of the Chinese Medical Association, 2009
A full-term female baby was admitted to our hospital at the postnatal age of 37 days with generalized vesiculopapular, crateriform skin lesions. Physical examination revealed a well-nourished baby without fever, hepatosplenomegaly or lymphadenopathy. Laboratory examination was normal except for thrombocytosis (platelet count, 970 x 10(3)/microL).
