Indeterminant Cell Histiocytosis in a Patient With Hemophagocytic Lymphohistiocytosis
The American Journal of Dermatopathology, 2021Abstract: Indeterminant cell histiocytosis is a rare disorder, which often presents as a benign, papular eruption without age or sex predilection. It is diagnosed based on histologic findings that are similar to those seen in Langerhans cell histiocytosis without the characteristic Birbeck granules.

Indeterminate Cell Histiocytosis: A Rare Histiocytic Disorder
The American Journal of Dermatopathology, 1997A 64-year-old woman, otherwise healthy, presented with multiple reddish-brown, slightly yellowish papules on the face and neck, which had developed 3 years earlier. The lesions were painless and nonpruritic and varied in diameter from 1 to 5 mm. Histological and immunohistochemical examination of cutaneous biopsies revealed a diffuse dermal infiltrate ...

Indeterminate Cell Histiocytosis of the Spine: A Case Report
Pediatric Neurosurgery, 2021<b><i>Introduction:</i></b> Indeterminate cell histiocytosis is a rare neoplastic disease characterized by proliferation of dendritic cells that share morphologic and immunophenotypic features of Langerhans cells and non-Langerhans histiocytes.

Indeterminate cell histiocytosis: fact or fiction?
Journal of Cutaneous Pathology, 2005Abstract: Indeterminate cell histiocytosis is a rare disorder, in which the predominant cells have the characteristics of both Langerhans cells and macrophages. We, in this study, describe 18 patients and compare them with those previously published. Most patients were adults with either solitary or multiple red‐brown papules or nodules.

Indeterminate cell histiocytosis successfully treated with ultraviolet B phototherapy
Clinical and Experimental Dermatology, 2008Indeterminate cell histiocytosis (ICH) is a rare disorder, characterized by infiltration of the skin by neoplastic cells that are characteristically positive for S-100 and CD1a, but lack Birbeck's granules. A 75-year-old man presented with a 4-year history of multiple papules on the trunk, limbs, face and neck.

Generalized Indeterminate Cell Histiocytosis Presenting as Eroded Papules and Crusts
The American Journal of Dermatopathology, 2017Abstract: Indeterminate cell histiocytosis (ICH) is a very rare histiocytic disease. We reported a case of generalized ICH presenting as eroded papules and crusts, accompanied with intermittent fever, pulmonary disorder, lymphadenectasis in the mediastinum, and the retroperitoneum.

An otherwise healthy 50-year-old woman presented with a 6-month history of having developed more than 100 generalized, non-confluent, reddish-brown, partially yellow-coloured papules. A non-epidemotropic, monomorphous infiltrate of vacuolated mononuclear, and occasionally multinuclear, histiocytes, positive for factor XIIIa and macrophage markers HAM56

Journal of Cutaneous Pathology, 2001
Background: Cutaneous indeterminate cell histiocytosis is a rare neoplastic disorder. Its varied histological presentation and rarity have limited efforts to determine its pathogenic relationship with other histiocytic lesions and possibly, its recognition.Methods: We report on an unusual histologic pattern of indeterminate cell histiocytosis that ...

A case of S‐100‐negative CD1a‐positive indeterminate cell histiocytosis
Journal of Cutaneous Pathology, 2019AbstractHistiocytoses are a group of rare disorders characterized by a proliferation of monocytes/macrophages and dendritic cells. We present a case of a 3‐year‐old girl with a diffuse papular eruption without systemic symptoms demonstrating a proliferation of strongly CD1a+ histiocytes, but negative for S‐100 and langerin on histopathology.

Abstract: Allogeneic hematopoietic stem-cell transplantation and solid-organ transplantation are associated with an increased risk of secondary neoplasms. Indeterminate cell histiocytosis (ICH) is a rare disease composed of so-called indeterminate cells, an alleged cutaneous dendritic cell subset displaying histological and some ...
