A variety of Tand B-cell neoplasm can involve the skin and the term “primary cutaneous lymphoma” refers to the disorder that present in the skin with no evidence of extracutaneous disease at the time of diagnosis [1,2]. Among them, primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL, LT) is characterized with skin lesions on one or both legs. In patients presenting with a single ...

Primary cutaneous anaplastic large T-cell lymphoma CD30+ is a rare lymphoma, which belongs to the group of lymphoproliferations CD30+. It characterized by an excellent prognosis and treatment therefore not very aggressive. However, its histological molecular characteristics have many similarities with lymphoproliferative diseases whose completely different. For this reason, it important study p...

We herein present the imaging findings in a case of diffuse primary cutaneous B-cell lymphoma of the cranial vault with orbital and brain invasion. MR imaging revealed first concomitant orbital and parenchymal invasion in a case of primary diffuse non-Hodgkin lymphoma of the cranial vault. Contrast-enhanced MR imaging revealed a diffuse mass in the scalp of the frontoparietal region bilaterally...

Cutaneous lymphomas are classified according to their cellular origin into T-cell lymphoma and B-cell lymphoma. The annual incidence rate is 0.3 per 100,000 population. We report a case of a 56-year-old male patient who presented with a two-month history of nodules of varying sizes, some ulcerated, on the face, abdomen, and upper limbs. Histopathological examination and immunohistochemical stud...

Primary Cutaneous lymphomas of B cell origin are rare, there remains a controversy in truly classifying these lymphomas and an updated EORTC classification divides them on the basis of their distinct histopthological grounds rather than on the basis of their anatomic location as in WHO classification, while the new WHO- EORTC joint classification maintains some characteristics of both systems, ...

BACKGROUND Primary cutaneous B-cell lymphoma typically localizes to the skin, and dissemination to internal organs is rare. Lymphomatous involvement of the breasts is also rare. We describe the clinical and radiological findings of an unusual case of primary cutaneous B-cell lymphoma presenting as an isolated breast mass without associated skin changes. CASE PRESENTATION The patient was a 55-...

BACKGROUND Distinct categories of skin lymphoma with preferential site localization and unique clinical behavior, including leg-type primary cutaneous diffuse large B-cell lymphoma, have recently been described. Although these entities are rare, they exhibit reproducible clinicopathologic features, and their recognition may allow more appropriate treatment protocols. OBSERVATIONS We describe ...
