primary cutaneous anaplastic large cell lymphoma is a t-cell malignancy with atypical cd30 positive lymphocytes. pseudoepitheliomatous hyperplasia is an uncommon finding in primary cutaneous anaplastic large cell lymphoma, and may mimic squamous cell carcinoma as pseudomalignancy. careful attention of a pathologist to correct diagnosis of pseudoepitheliomatous hyperplasia and its underlying cau...

Primary breast lymphoma represents less than 1% of all primary breast malignancies and most primary breast lymphomas are of B-Cell origin. The association of anaplastic lymphoma kinase (ALK) negative anaplastic large cell lymphoma (ALCL), a very rare form of primary breast lymphoma, with silicone-filled breast implants has been suggested and several case reports supported this proposal, especia...

background and objective: inflammatory pseudotumor  is a lesion composed of proliferating spindle cells with mixed inflammatory infiltrates. some authors have proposed the name inflammatory myofibroblastic tumor as a proper descriptive term rather than the vague inflammatory pseudotumor. the aim of this study was to verify the myofibroblastic origin of spindle cells in idiopathic orbital inflam...

background: breast implant associated anaplastic large t- cell lymphoma is a rare type of non-hodgkin lymphoma, with a reported incidence of 0.3% per 100,000 women with breast prosthesis per year. it presents most commonly as a peri-implant seroma, but may also present as a capsular mass, tumor erosion through skin, in a regional lymph node, or found incidentally during revision surgery. case p...

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. excisional biopsy was performed. flow cytometry was non-diagnostic. she conti...

background & objectives: anaplastic lymphoma kinase (alk) is a receptor tyrosine kinase involved in the genesis of several human cancers. alk was initially identified because of its involvement in anaplastic large cell lymphoma (alcl). alk is believed to foster tumorigenesis following activation by autocrine and/or paracrine growth loops. studies reveal that the presence of anti-alk antibod...

abstract inflammatory pseudotumour describes as a wide range of neoplastic and reactive lesions. one of the rare presentations of these tumors is found in the salpinx. this case report characterizes a thirty six year old woman with a history of left sided abdominal pain for a few months. further examinations revealed that she had a complex cyst in her left salpinx. the patient had normal levels...

here, we report on a ten-year-old girl with chronic draining nonhealing ulcer in her neck and unilateral cervical chronic lymphadenopathy. her ulcer had poor clinical response to broad spectrum antibiotics and anti-tuberculosis treatment. she had undergone several wound biopsies with no conclusive results. she was otherwise healthy with no known underlying disease. final wound excisional biopsy...
