Lichen aureus is a variant of pigmented purpuric dermatoses. The usual histopathology lichen characterized by subepidermal dense, band-like lymphocytic infiltrate, extravasated erythrocytes, and hemosiderin deposits. We report three patients with on the extremities similar clinical, dermoscopic, histopathological findings dense relatively deep dermal infiltrate accompanied extravasation erythro...
Autoimmune lymphoproliferative Syndrome (ALPS) is a rare inherited disorder of apoptosis. It usually presents with chronic lymphadenopathy, splenomegaly, and symptomatic cytopenia in a child. Herein, we report a 14-year-old boy with symptoms misdiagnosed as hemophagocytic lymphohistiocytosis who was treated before ALPS was diagnosed for the patient. This case should alert pediatricians to consi...
Advances in flow cytometry techniques and the availability of monoclonal antibodies that detect key functional molecules on lymphocytes have contributed greatly to a more precise diagnosis of the chronic lymphoproliferative disorders. In addition to the diagnostic value, the expression of certain markers such as p53 or CD38 provides relevant prognostic information to the clinician. Beyond their...
Necrobiotic xanthogranuloma (NXG) is a rare systemic disease primarily associated with cutaneous plaques; these plaques can manifest anywhere, but most commonly affect the face and periorbital regions. It has a distinct histopathology with extensive necrobiosis and infiltrates of inflammatory cells. Patients with NXG are often found to have paraproteinemia or hematologic disorders, including mu...
Multiple methods, pedigree analysis, clinical evaluation, and Epstein-Barr virus (EBV)-specific serology, EBV DNA hybridization of tissues to probe for viral genome, staining of touch imprints for EBV nuclear-associated antigen, establishment of spontaneous infected B-cell lines from peripheral blood or tissues, examination of peripheral blood smears, and hematopathology studies, were used to s...
It is well known that patients with lymphoproliferative disorders have an altered immune status and are susceptible to opportunistic and non-opportunistic infections. The authors report the first case of a patient with advanced Hodgkin's disease who developed pneumonia caused by the animal pathogen Bordetella bronchiseptica. The most likely source ofthis organism was the patient's dog. While B....
Autoimmune lymphoproliferative syndrome (ALPS) is an uncommon nonmalignant lymphoproliferative disease which is characterized by chronic, persistent or recurrent lymphadenopathy, splenomegaly, hepatomegaly, immune cytopenia , hypergammaglobinemia and increased risk of lymphoma. We report a 2-year old boy with hepatosplenomegaly as first presentation. Petechial and purpuric rashes with massive c...
The spectrum of CD30+ lymphoproliferative diseases of the skin includes CD30+ cutaneous anaplastic large cell lymphoma, lymphomatoidpapulosis, as well as borderline cases. These entities constitute the second most common group of cutaneous lymphomas according to the newly revised World Health Organization and European Organisation for Research and Treatment of Cancer consensus classification. R...
Lymphomatoid granulomatosis (LYG) is an angiocentric and angiodestructive lymphoproliferative disease involving extranodal sites. Although LYG cerebral lesions are usually located adjacent to LYG pulmonary lesions, few reports have described the occurrence of primary cerebral LYG. We herein discuss a case of a 40-year-old Japanese woman with primary cerebral LYG that caused various neurological...
Acquired C1 inhibitor deficiency: Clinical manifestations, epidemiology, pathogenesis, and diagnosis
INTRODUCTION — Acquired deficiency of C1 inhibitor (C1-INH), also called acquired angioedema (AAE), is a rare syndrome of recurrent episodes of angioedema, without urticaria, which is associated with B cell lymphoproliferative disorders in some patients [1,2]. Angioedema typically affects the skin or mucosal tissues of the upper respiratory and gastrointestinal tracts. The swelling is self-limi...
