Langerhans’ cell histiocytosis diagnosed due to dermatological perianal lesion

Journal of Coloproctology, 2017
Langerhans’ cell histiocytosis is a rare disease characterized by proliferation of Langerhans cells in the body. It affects mainly males, predominantly in childhood. Ulcerated plaques are one of the cutaneous forms of presentation.

The Potentials and Pitfalls of a Human Cervical Organoid Model Including Langerhans Cells

Viruses, 2020
Three-dimensional cell culturing to capture a life-like experimental environment has become a versatile tool for basic and clinical research. Mucosal and skin tissues can be grown as “organoids” in a petri dish and serve a wide variety of research ...

Florid dermatopathic lymphadenopathy—A morphological mimic of Langerhans cell histiocytosis

Clinical Case Reports, 2018
Key Clinical Message The histopathology of reactive florid dermatopathic lymphadenopathy shows overlap with Langerhans cell histiocytosis (LCH) involving the lymph node, which may lead to misdiagnosis.

Adult-onset perianal Langerhans cell histiocytosis presenting as pruritus ani: a case report and review of the literature

Journal of Medical Case Reports, 2021
Background Langerhans cells belong to the histiocytic system and give rise to two tumors: Langerhans cell histiocytosis and Langerhans cell sarcoma. Clinical aggressiveness and degree of atypia distinguish the two neoplasms. Langerhans cell histiocytosis

A Precision‐Delivered Singlet Oxygen Generator With an Inbuilt Safety Switch for Induction of Pancreatic Beta Cell Stress and Death

Angewandte Chemie, EarlyView.
ROXendin668 is a peptidic GLP‐1 receptor agonist that generates toxic singlet oxygen upon irradiation with far‐red light. Pancreatic beta cells can be photo‐ablated in a spatiotemporally controlled manner. This approach has the potential to provide a safer alternative to streptozotocin or alloxan for creating model systems for type 1 diabetes research.

Rho-associated kinase regulates Langerhans cell morphology and responsiveness to tissue damage

Cell Reports
Summary: Skin damage requires efficient immune cell responses to restore organ function. Epidermal-resident immune cells known as Langerhans cells use dendritic protrusions to surveil the skin microenvironment, which contains keratinocytes and peripheral

Langerhans cell histiocytosis presenting as a blueberry muffin rash

Dermatology Reports, 2023
Langerhans cells, often referred to as the “macrophages of the skin”, are dendritic cells that normally reside in the epidermis and papillary dermis. Just like macrophages, they function as antigen-presenting cells that activate naive T cells.
