*3.1.1.1.1 Maculopapular sarcoidosis*

Lesions of maculopapular sarcoidosis are usually red-brown to purple in color and less than 1 cm in diameter. Sometimes they may be skin-colored, yellow-brown, or hypopigmented. They are slightly infiltrated, with little epidermal change. They are located on the face, particularly on the eyelids, around the orbits and the nasolabial folds, and on the scalp, occipital area of the neck, trunk, buttocks, and extremities (**Figure 1**). Lesions are commonly disseminated, and mucous membranes may even be involved [7, 9–11]. Diascopy shows the typical apple-jelly color characteristic of granulomatous skin lesions. These lesions are sometimes transient and appear to herald the onset of the disease [11]. Patients with papular lesions had a mean age of 47 years (9–83 years), and the usual duration of disease to heal is less than 2 years [12]. Acute organ involvement, such as sudden lymphadenopathy, acute arthritis, and acute uveitis abnormal chest radiographs, has been associated with this type of

eruption [9]. The intrathoracic involvement occurs in the early stage of the disease, bilateral hilar lymphadenopathy with or without parenchymal infiltration (up to stage II) (60%), and lymphadenopathy in 50% of the patients [13].
