Intravascular Histiocytosis in a Patient with Rheumatoid Arthritis / 대한류마티스학회지

Intravascular histiocytosis is an unusual cutaneous lesion with massive aggregates mainly composed of histiocytes in markedly dilated dermal vessel and previously reported in associations with rheumatoid arthritis (RA). We report a case of intravascular histiocytosis in RA patient. A 58-year-old woman having 20-year history of RA presented with the right elbow pain and poorly demarcated, indurated erythema in the right forearm. Biopsy revealed vascular proliferation and mononuclear cellular aggregates in the dilated vessels of dermis. Immunohistochemical findings of the intravascular cells were consistent with a histiocytic differentiation. She underwent synovectomy in the right elbow joint and had rapid resolution of cutaneous lesion.

A case of ovarian fibrothecoma with Mature teratoma of the Ipsilateral Ovary and ovarian fibroma of the contralateral Ovary / 대한산부인과학회잡지

Fibrothecoma are mesenchymal tumors deriving from the ovarian stroma and consisting of theca-like elements and fibrous tissue. The reported incidence is between 0.4 and 8.0% of all ovarian tumors and this side variability can be attributed to the difficulty in differentiation fibrothecoma from ovarian fibroma or hyperplastic stroma nodules. A dermoid cyst is composed of well-differentiated derivatives of the three germ layers; ectoderm, mesoderm, and endoderm. We have experienced a case of ovarian fibrothecoma with mature cystic teratoma of the ipsilateral ovary and ovarian fibroma of the contralateral ovary in a 33-year-old woman. We report a case with brief review of literature.
