Large-Cell Acanthoma

The American Journal of Dermatopathology, 1992
Large-cell acanthoma is an epidermal neoplasm that is clinically, histologically, and biologically distinctive. Clinically, it differs from solar lentigo by being frequently skin-colored or hypopigmented. Histologically, it is defined by a population of uniformly large keratinocytes; it differs from solar lentigo by the absence of elongated ...

Anaplastic large-cell lymphoma

Seminars in Diagnostic Pathology, 2011
The concept of anaplastic large-cell lymphoma (ALCL) has changed over the years because of a stream of new information and novel understanding regarding the cell of origin, biology, genetics, and clinical features of these neoplasms. This new information has led to the current classification proposed by the expert reviewers of the World Health ...

Anaplastic Large Cell Neuroblastoma

Pediatric and Developmental Pathology, 2009
Anaplastic large cell neuroblastomas (ALCNB) are a subset of undifferentiated neuroblastomas with marked pleomorphic and anaplastic features that render them diagnostically challenging. We reviewed the records of all patients diagnosed with ALCNB at Children's Healthcare of Atlanta (Egleston Children's Hospital) for their clinical, biologic, and ...

Large cell/neuroendocrine carcinoma

Lung Cancer, 2010
Large cell neuroendocrine tumors of the lung represent a recently reclassified subtype of lung cancer with features of both small cell and non-small cell lung cancer. We review diagnostic difficulties, typical presentations, and the natural history of this tumor.

Anaplastic Large Cell Lymphoma

2014
Anaplastic large cell lymphoma (ALCL) is a rare lymphoid malignancy that is characterized by the expression of CD30 cell surface receptor and by a chromosomal translocation that results in aberrant constitutive activation of the anaplastic large cell lymphoma kinase (ALK).
