- A case of malignant eccrine acrospiroma of the anterior chest wall is reported. This mass had been present for 20 years and during rescent 5 years it showed frequent ulceration and bleeding suggesting malignant transformation.
Microscopically, several foci malignant transformation from preexisting benign eccrine acrospiroma are seen and in immunohistochemical staining, the tumor cells both benign and malignant portion, show positive reaction to cytokeratin.

Abstract
PDF
- Angiofollicular lymph node hyperplasia(AFLNH) was first described in 1956 by Castleman et al. It was initially reported as a solitary mediastinal mass but multicentric and extranodal disease is now well known. Histologically two distinct variants, e.g. the hyaline vascular type and the plasma cell type, of AFLNH are recognized. And the plasma cell type is typically associated with clinical syndrome consisting of fever, anemia, elevated erythrocyte sedimentation rate and polyclonal hypergammaglobulinemia.
Recently, we experineced three cases of AFLNH.
Histologically, two cases were hyaline vascular type, that were presented as a right supraclavicular mass of 49-year-old female, and as an anterior mediastinal mass of 53-year-old female. The remaining one case was plasma cell type that was presented as a left axillary mass of 63-year-old male. The former two cases showed typical features of hyaline vascular type but in case 1, exuberant proliferation of hyalinized vessels of capillary size was characteristic feature. The latter case of plasma cell type characteristically showed clinical syndrome consisting of fever, hypoalbuminemia, polyclonal hypergammaglobulinemia.
All cases were presented as a single mass and they were well after surgical excision.

Abstract

- Cytophagic histiocytic panniculitis is a rescently described histiocytic disorder. It is characterized by the presence of fever, pancytopenia, and subcutaneous nodules resulting from the infiltration of lympho-histiocytes in the dermis and subcutaneous adipose tissue. The characteristic findings is presence of bean-bag histiocytes containing phagocytized red blood cells, lymphocytes, and platelets. We experienced two cases of cytophagic histiocytic panniculitis with hard and erythematous subcutaneous nodules. These skin lesions exhibited infiltration of the subcutaneous tissue by large, benign histiocytes with cytophagic features. Hemophagocytic histiocytes were observed in the cervical lymph node in case 1, and bone marrow in case 2. One patient is alive, while the other one died with hemorrhagic complications.

Abstract

- We report an autopsy case of amniotic band syndrome exhibiting microcephaly, asymmetric encephalocele, microphthalmia, nasal deformity, cleft lip and palate accompanied by left maxillary and zygomatic bone deformities. The amniotic membrane of the placenta was also attached to the herniated brain. The twenty-year-old primigravid mother had no history of taking drug, irradiation, infection or trauma before or during pregnancy.

Abstract
PDF
- Ki-1 monoclonal antibody is a well known marker for Reed-Sternberg cells in Hodgkin's disease, but also occasionally reacts with activated lymphoid cells of either benign or malignant nature. Recently, Ki-1 antibody positive Non-Hodgkin's lymphoma, usually of large cell and/or polymorphous type, has been reported in the lymph nodes, skin, soft tissue, and stomach, but not in the bone. We report a case of multifocal primary bone lymphoma in a seven-year old body involving the left shoulder and right frontal bone, which proved to be a large cell, polymorphous lymphoma, helper T-cell type expressing Ki-1 antigen.
