Introduction
Indeterminate cell histiocytosis (ICH) is a rare histiocytic proliferative disease, which was first described by Wood et al.in 1985. It predominantly affects adults with no gender predilection. Further, its pathogenesis remained unknown, and presents as solitary or generalized lesions [1]. Solitary or multiple papules and/or nodules which usually runs a benign process are the general presentation of ICH. Diagnosis of ICH is based on the clinical features, immunophenotype and histopathology. There is a relationship between ICH and cancer, especially on the hematopoietic malignancy and follicular lymphoma [2]. In this study we report a case of cutaneous indeterminate cell histiocytosis following esophageal carcinoma and followed by bullous pemphigoid.
