Squamoid Eccrine Ductal Carcinoma: Case Series of a Rare, Potentially Aggressive Skin Cancer Associated With Immunosuppression

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Squamoid Eccrine Ductal Carcinoma (SEDC) is a rare cutaneous adenexal carcinoma first described in 1997. It has distinct biphasic features on histology which commonly result in misdiagnosis as Bowen disease or cutaneous squamous cell carcinomas (cSCC) if diagnostic skin biopsies are too superficial. This may lead to a delay in diagnosis. It is

Superficial Ewing Sarcoma of the Rectum: A Case Report and the Utility of Molecular Diagnostics

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Ewing sarcoma is an undifferentiated small round cell sarcoma that most commonly presents as a malignant bone tumor in pediatric and young adult patients. The diagnosis is typically confirmed by molecular genetic identification of a fusion protein, most commonly involving members of the FET and ETS gene families.

Merkel Cell Carcinoma With Divergent Differentiation—Or Something Else? A Triphasic Cutaneous Carcinoma With Lineage Plasticity

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous neuroendocrine carcinoma that typically arises in sun‐exposed skin of older or immunosuppressed patients. Combined or collision tumors involving MCC and other cutaneous malignancies are uncommon, and tumors exhibiting more than two distinct malignant phenotypes are exceptionally rare.

Primary Cutaneous Gamma‐Delta T‐Cell Lymphoma Complicating Long‐Standing Immunosuppressed Dermatomyositis

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Primary cutaneous gamma‐delta T‐cell lymphoma (PCGD‐TCL) is a rare cytotoxic lymphoma with key oncogenic drivers in the JAK/STAT pathway. Also primarily involving the subcutaneous adipose tissue, subcutaneous panniculitis‐like T‐cell lymphoma (SPTCL) is more frequently encountered in scenarios of autoimmune disorders.

Fibrillar‐Type Dermatitis Herpetiformis: An Underrecognized Variant That Is Rarely Associated With Celiac Disease and Lacking Epidermal Transglutaminase Deposition: A Report of Two Cases

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Dermatitis herpetiformis (DH) is a rare, intensely pruritic cutaneous manifestation of celiac disease (CD), typically presenting with excoriated papulovesicular lesions on extensor surfaces. DH is associated with IgA autoantibodies against epidermal transglutaminase (eTG), which form granular immune deposits in the papillary dermis and induce ...
