Near early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) is a rare hematologic malignancy, for which second line therapeutic options are limited. T-cell leukemias are also rarely associated with leukemia cutis, which is more often seen in leukemias of myeloid origin. We present the case of an adult male diagnosed with near ETP-ALL, with IDH2 and DNMT3A mutations, suggestive of a myeloid origin, and leukemia cutis.

Prognostic factors for melanoma include Breslow depth (BD), ulceration, and dermal mitotic rate (DMR). No studies have queried the effect of epidermal mitotic density (EMD) or atypical mitotic figure density (AMD) in an outcome-based assessment. Our objective was to determine if there is a relationship between EMD, AMD, BD, DMR, and ulceration and patient outcomes.

Article Synopsis
  • There are two rare types of cancer mentioned: one that happens on the skin and another related to breast implants.
  • A unique case is described where a person developed a type of this cancer in the skin near their breast after having breast implants and a history of breast cancer.
  • The cancer cells are only found in the skin's lymphatic system, and the patient has no other signs of illness or fluid buildup around the implants.

Cutaneous sclerosis occurs in association with a variety of systemic diseases, including hematologic malignancy, plasma cell dyscrasias, solid organ tumors, and other systemic autoimmune conditions. Herein, we present a unique case of morphea/lichen sclerosus overlap arising in association with aplastic anemia. To expand upon this rare case, we also review the literature surrounding paraneoplastic sclerosing skin disorders.

New American Joint Committee on Cancer eighth edition staging parameters have removed mitotic rate as a stage T1 category criterion, but it remains embedded in the synopsis of primary cutaneous melanoma (CM). A paucity of data is available, characterizing atypical mitotic forms in CM. In this study, we classify the various morphologic forms of atypical mitoses, characterize mitotic figure density, and examine the correlation between atypical mitotic figures and Breslow depth.

Primary central nervous system melanoma is rare and characterized by a variable prognosis, and no current treatment guidelines exist. We describe the clinical course of a 70-year-old female patient diagnosed with primary leptomeningeal melanoma (LMN) whose case represents the diagnostic and management challenges of this tumor. Targeted genomic sequencing of 315 genes from this tumor revealed GNAQ Q209L mutation and low (4 mutations/Megabase) tumor mutation burden (TMB).

Leukemia cutis, or infiltration of leukemic cells into the skin, occurs rarely in B-cell acute lymphocytic leukemia (ALL). Herein, we have described a rare, precocious presentation of B-cell ALL presenting as indurated facial plaques in a 69-year-old man. Biopsy of the facial plaques revealed precursor B-cell leukemia/lymphoma in the skin and prompted urgent hematologic-oncologic evaluation.

Scabies surrepticius is a unifying term that represents non-classical presentations of scabies mite infestation. A patient with scabies surrepticius is described: a man with scabies masquerading as prurigo nodularis. The 91-year-old man had metastatic prostate cancer and presented with diffuse pruritic nodules.

The histologic profile of discoid lupus erythematosus typically involves a vacuolar interface reaction with an associated superficial and deep perivascular infiltrate composed of lymphoplasmacytes. We present a unique case of discoid lupus erythematosus in which cluster of differentiation 68 (CD68) immunochemistry identified widely dispersed histiocytes. Few reports of histiocyte-rich cutaneous lupus erythematosus exist in the literature, and these lymphohistiocytic infiltrates, when present on the H-zone of the face, could be misconstrued as acne/rosacea.

Background Acquired elastotic hemangioma is a benign vascular proliferation that typically presents as an asymptomatic red plaque on a sun-exposed site of an adult. Material and Methods The PubMed database was used to search the following words: acquired, angioma, arm, basal, carcinoma, cell, elastosis, elastotic, exposed, forearm, hemangioma, solar, sun, and vascular. The relevant papers and reference cited generated by the search were reviewed.

Erythroderma is characterized by erythema involving greater than 90% of the body surface area and may be caused by several etiologies, including erythrodermic psoriasis. Psoriasis is an autoimmune skin and systemic condition characterized by erythematous and scaly plaques. Monoclonal B-cell lymphocytosis is an asymptomatic hematological disorder diagnosed by elevated, small, clonal B-cell counts in the peripheral blood.

Neutrophilic urticarial dermatosis (NUD) is a useful diagnostic term for urticarial lesions that are less pruritic and more painful than conventional urticaria. The histopathologic features include neutrophilic infiltrates in the interstitial dermis with a higher density than idiopathic urticaria. NUD has been associated with several systemic conditions, which are predominantly autoimmune and autoinflammatory in nature.

Plasma cell leukemia is an uncommon, aggressive variant of leukemia that may occur de novo or in association with multiple myeloma. Leukemia cutis is the cutaneous manifestation of leukemia, and indicates an infiltration of the skin by malignant leukocytes or their precursors. Plasma cell leukemia cutis is a rare clinical presentation of leukemia.

Background: Sclerosing mesenteritis is a rare disease of unknown etiology that is characterized by self-limited, nonspecific inflammation and fibrosis of the mesenteric adipose tissue. Histologic classification characterizes 3 main stages in the evolution of the fibroinflammatory process: mesenteric lipodystrophy (ML), mesenteric panniculitis (MP), and sclerosing (retractile) mesenteritis (SM).

Observations: A 68-year-old woman with biopsy-proven MP presented with multiple asymptomatic, indurated subcutaneous nodules on both arms, as well as 2 indurated plaques on her abdomen.
