Anaplastic Large Cell Lymphoma Associated With Breast Implants

A forty two years old woman with a history of bilateral breast augmentation for cosmetic reasons was presented for poor healing of the surgical site. Tissue and periprosthetic fluid were removed from the wound site revealing an atypical lymphoid infiltrate. Subsequently the patient developed axillary lymph adenopathy.

Anaplastic large cell lymphoma presenting as a cerebellar mass.

Anaplastic large cell lymphoma (ALCL) is a T cell lymphoma occurring commonly in childhood and rarely in adults. Central nervous system involvement in ALCL is very rare and cerebellar involvement at presentation has never been described. We examine the case of a young adult who presented with a cerebellar mass. A 19-year-old boy presented with signs of raised intracranial tension, which, on ima...

Primary gastric anaplastic lymphoma kinase-negative anaplastic large-cell lymphoma

INTRODUCTION Most primary stomach lymphomas are now recognized to originate from B-cell. Primary gastric anaplastic lymphoma kinase (ALK)-negative anaplastic large-cell lymphoma (ALCL) as shown in this case is very rare. CASE REPORT A 59-year-old man presented with a 1-month history of epigastric pain. Computed tomography showed a tumor in the stomach with perigastric lymphadenopathy. Biopsy ...

Anaplastic large cell lymphoma (ALCL)

Note Anaplastic large cell lymphoma can be classified into: 1Primary systemic ALK+ ALCL, 2Primary systemic ALKALCL, 3Primary cutaneous ALCL (see in paragraph Pathology). The 2 first categories are defined according to the involvement (or not) of ALK in fusion proteins with various partners (see below); ALK+ ALCL cases are sometimes called ALK lymphomas, or ALKomas. ALK+ ALCL can be further divi...
