The finding of cohesive, branching keratinized squamous cell clusters admixed with sebaceous cells may suggest a diagnosis of trichofolliculoma, as was seen in the present case. [mayoclinic.pure.elsevier.com]

Findings in NLCS are reminiscent of fetal adipogenesis; pinocytosis and condensation of the plasma membrane and the many vascular elements in contact with adipocytes suggest a vascular origin of the adipose cells. [e-ijd.org]
