The clinical characteristics of primary cutaneous CD30-positive large cell lymphoma are solitary or localized skin lesions, frequent relapses, spontaneous regression and a favorable prognosis. These relapses and spontaneous regressions occur frequently in borderline cases between CD30-positive large cell lymphoma and lymphomatoid papulosis. Regression and relapse, which occurs in both cutaneous CD30 positive large cell lymphoma and lymphomatoid papulosis, dose not help distinguish one from the other. We report two cases diagnosed as clinically and histologically primary cutaneous CD30-positive large cell lymphoma, recurred respectively on the same anatomic site and on the different anatomic site.

Lymphomatoid papulosis(LyP) is a chronic recurrent dermatosi characterized by involuting and recurring papules, plaques, and nodules showing histologic feaurs suggesting rnalignant lymphoma. On histologic ground, it is divided into two types. type A and type B. In type A, large atypical lymphocytes are the main cellular cornponent and most of these express CD 30(Ki-1) antigen, which has been p!reviously thought to be specific for Read Sternberg cells of Hodgkins disease. In type B, cerebriform mononuclear lymphocytes sirr la to those in mycosis fungoides predominates. We report two cases of lymphomatoid papulosis, type A and type B, respectively. The large atypical cells in type A LyP expressed Ki 1 antigen. Both case were treated with PUVA and the outcome of the treatment has been fair.

Lymphomatoid papulosis, first described by Macaulay in 1558 is a chronic disease characterized by the recurrent self-healing papulonecrotic or nodular skin lision, showing histological features of malignant lymphoma. The clinical course is variable, with rogression to disseminated malignant lymphoma in up to 10-20% of patients. Ki-1 appears to the a representative marker for large cells ir lymphomatoid papulosis and these cells can be detected in l-1 lymphorna, Hodgkins diseasen other disorders with aetivated T cells. However, positive Ki-1 staining is useful for supporting a diagnosis of lymphomatoid papulosis, under the appropriate clinical and histopathologic findings. We report a case of positive lymphomatoid papulosis which is characterized by the typical findings of clinical, histojpathological and immunohistochemica sizdies.

Lymphomatoid papulosis(LyP) is a chronic recurrent self-healing condition, with histological features suggestive of a malignant lymphoma. LyP usually develops in adults and lesions occur episodically over the trunk and limbs. Lymphomatoid papulosis has been reported only rarely in children. Furthermore localized and regional forms of lymphomatoid papulosis have been described very rarely. We report a case of CD30(Ki-1) positive LyP developed in childhood who had recurrent skin lesions confined to the face.
