ABSTRACT
Cutaneous disease can present with lesions of all colors of the visible spectrum. Lesions of the skin, nail, and mucous membranes with an orange color can be due to a variety of etiologies. The conditions may appear as purely orange, yellow-orange, red-orange, tan, or brown with an orange hue. The orange color may also present as a transient phase of a disease process. As with all dermatologic pathology, a key way to distinguish orange-colored lesions is by distribution and morphology. The sclera, palate, lips, gingiva, and nails may also be involved. A literature review using PubMed with keywords, including orange, skin, mucosa, cutaneous, xanthoderma, and granuloma, was conducted to gather all dermatologic conditions that can present with an orange color. The relevant diseases were categorized by etiology and include inflammatory, infectious, neoplastic, and exogenous causes.

Langerhans cell histiocytosis and mastocytoma are clonal disorders of bone-marrow-derived cells, most commonly seen in the pediatric age. Infiltration of mast cells and Langerhans cells in the same lesion has been published before, but, to our knowledge, this is the first time that the occurrence of two mastocytomas and Langerhans cell histiocytosis is reported. It could be hypothesized that both clonal disorders of bone-marrow-derived cells could have a common origin.
