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, 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 defined as a histologically malignant, but clinically benign condition. It can appear as erythematous pink to purple papules or nodules. Immunophenotyping studies of the lymphomatoid papulosis lesions have shown a predominance of a CD4 expression and negativity for CD8. However, a positive CD8 expression has rarely been reported for LyP. Herein we report on a case of CD8 positive lymphomatoid papulosis in a 43-year-old man. The patient presented with erythematous, asymptomatic papules on the left axilla and thigh. Histopathologically, there was a wedge-shaped infiltrate composed of a mixture of various cell types, including lymphocytes, histiocytes, neutrophils and large atypical lymphoid cells. Immunophenotyping revealed the neoplastic cells were positive for CD3, CD8 and CD30 and they were negative for CD4, CD20 and CD56.

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.
