Melanocytic Panfolliculoma: A Case Report of a Rare Benign Follicular Tumor.

Panfolliculomas (PF) are rare, benign, follicular tumors that differentiate toward multiple components of the hair follicle, and several variants have been described. We present a case of a rare pigmented PF presenting on actinically damaged skin in an 83-year-old man, which was clinically concerning for malignancy. This tumor arose near an area of atypical squamous proliferation and has evidence of infundibular, outer root sheath, and matrical differentiation and foci of heavy melanin pigmentation and increased melanocytes.

A meissnerian neurofibroma: Case report of a rare neurofibroma variant.

Structures resembling Meissner corpuscles have been described in various nerve sheath tumors, including schwannomas and neurofibromas. When present, they are focal or scattered, and rarely a prominent feature of the lesion. Here, we report a case of a 39-year-old female who presented with an isolated lesion on her abdomen.
