Abnormal hair development and regeneration occurs in some skin diseases, including lymphomas when hair follicles are eliminated. Otherwise, neoplastic cells, both malignant and benign, local occurring and metastatic, can cause alopecia of the scalp. In lymphomas alopecia can develop due to direct infiltration by the disease, or it may be a secondary or paraneoplastic manifestation. Total -body ...

Pagetoid reticulosis is a rare variant of mycosis fungoides that presents with a large, usually single, erythematous, slowly growing scaly plaque containing an intraepidermal proliferation of neoplastic T lymphocytes. Histopathologically, this disease has distinctive attributes. In this report, we present two cases of pagetoid reticulosis, compare its microscopic features to those of 'classical...

Previous cytogenetic studies of primary cutaneous T-cell lymphoma (CTCL) were based on limited numbers of patients and seldom showed consistent nonrandom chromosomal abnormalities. In this study, 54 tumor DNA samples from patients with CTCL were analyzed for loss of heterozygosity on 10q. Allelic loss was identified in 10 samples, all of which were from the 44 patients with mycosis fungoides (1...

ALCL: anaplastic large cell lymphoma CL: composite lymphoma EBV: Epstein-Barr virus MF: mycosis fungoides INTRODUCTION Patients with mycosis fungoides (MF) are at increased risk of a second malignant neoplasm, especially lymphoma. We report a sexagenarian with a 14-year history of patch MF, stage IB, who had intravascular cutaneous anaplastic large cell lymphoma (ALCL) and cutaneous composite l...

A patient with mycosis fungoides developed a nephrotic syndrome. Renal biopsy revealed deposits of a highly organized fibrillar material which did not stain with the typical amyloid stains; this picture was consistent with the diagnosis of non-amyloidotic fibrillary glomerulopathy or immunotactoid glomerulopathy. We believe this is the first case reported of immunotactoid glomerulopathy associa...

We report a case of intraocular mycosis fungoides in a 48-year-old man. The patient presented with decreased visual acuity, white subretinal lesions, and vitritis. Post-mortem histopathology revealed malignant T cell infiltrates consistent with mycosis fungoides in the retina, vitreous, and between the retinal pigment epithelium (RPE) and Bruch's membrane Focal atrophy of the RPE, along with th...
