Novel report of an osteogenic tumor in a late Jurassic Mamenchisaurid from Thailand
Journal of Anatomy, EarlyView.Here we describe a pathology in an ulna of a Late Jurassic mamenchisaurid from Thailand. We use anatomical descriptions, CT scanning, and bone histology to identify the pathology as an osteogenic tumor. Abstract Here we report on an osseous abnormality and multiple fractures in an ulna of a subadult basal Eusauropod (Mamenchisauridae) from the Late ...

BRAFV600E mutation in cutaneous lesions of patients with adult Langerhans cell histiocytosis. [PDF]
, 2015 BACKGROUND: Langerhans cell histiocytosis (LCH) is characterized by the proliferation of pathologic Langerhans cells. The disease can develop in any age and can affect almost any organ. Cutaneous involvement is frequent in LCH.

Steroid‐responsive generalised sterile necrotising pyogranulomatous lymphadenitis in a cat
Journal of Small Animal Practice, EarlyView.A 1.5‐year‐old neutered male cat was presented with fever, inappetence, lethargy and marked generalised lymphadenopathy of 4 days duration. Excisional biopsy of peripheral lymph nodes revealed necrotising pyogranulomatous lymphadenitis. Extensive investigation failed to identify an underlying infectious [bacterial (Bartonella, Mycobacteria, Mycoplasma,

Impact of BRAFV600E mutation on aggressiveness and outcomes in adult clonal histiocytosis
Frontiers in Immunology, 2023 Histiocytoses encompass a wide spectrum of diseases, all characterized by tissue infiltration by CD68+ histiocytes. Most adult histiocytoses are considered clonal diseases because they highlight recurrent somatic mutations in the MAP-kinase pathway gene,

Histiocytoid Sweet Syndrome With Paradoxical Neutropenia in a Pediatric Patient
Pediatric Dermatology, EarlyView.ABSTRACT Histiocytoid Sweet syndrome (HSS) is a rare inflammatory skin condition characterized by the infiltration of mononuclear cells in the dermis and leukocytosis with neutrophilia. This uncommon variant of classic Sweet syndrome is rarely reported in the literature, especially in pediatric patients.
