Article Synopsis
- Trichofolliculoma is a rare, non-cancerous skin tumor that typically appears in adults, affecting mainly the face and scalp, and is characterized by small hairs protruding from papules or nodules.
- The exact cause of this tumor is not well understood, and it does not seem to favor one gender over another.

College of Veterinary Medicine, National Pingtung University of Science and Technology, Neipu, Pingtung County 912301, Taiwan.
Compared to the number of studies on the neoplasms of laboratory rodents, fewer studies have focused on spontaneous neoplasms in pet rodents. Notably, the mouse mammary tumor virus (MMTV) is associated with mammary tumors in rodents. In this study, 77 tumors and tumor-like lesions of biopsy samples were collected from 70 pet rodents, including hamsters (n = 47), guinea pigs (n = 16), unknown species (n = 4), rats (n = 2), and a gerbil.

MioGreensumer Pathology Clinic, Incheon City, Korea.
Article Synopsis
- - Nevus lipomatosus superficialis (NLS) is a rare benign growth of fat tissue that has been minimally reported over the past century; a case involving a 41-year-old man with a lesion near his right ear was treated and analyzed.
- - A literature review of 158 articles on NLS found 112 that met the study's criteria, detailing 149 cases, and highlighted the importance of recognizing NLS, especially when it appeared alongside conditions like sebaceous trichofolliculoma.
- - Although NLS is typically asymptomatic and benign, it can sometimes become problematic due to its size or location, so early identification and treatment are essential for the best outcomes.

Article Synopsis
- Tumor of follicular infundibulum (TFI) is a controversial neoplasm that can occur alone or with other skin lesions, leading to varied definitions in histopathology.
