It usually presents in males in the first two decades of life, and the most common presentation is a solitary asymptomatic papule or nodule varying from 5 mm to 1‒2 cm in size, with a translucent, smooth, yellowish to brownish surface and occasional telangiectasias. In adults, this lesion tends to persist over time, rather than involute with time as in children. Adult and juvenile xanthogranulomas are usually located in the head and neck region, followed by the trunk and extremities; however, all cutaneous locations have been described, including palms and soles.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> Case reports including cases of JXG on the volar surfaces (palms and soles) have described unusual colors appearing in this location, such as dull red or flesh-colored, and a well-defined hyperkeratotic peripheral rim upon dermoscopy.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> Typical dermoscopic findings of adult and juvenile xanthogranuloma include a yellow/orange and red/pink homogeneous background, often referred to as the ‘setting sun’ pattern.<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">4</span></a> Clinical differential diagnosis includes several benign and malignant tumors, such as Spitz nevus, dermatofibroma, adnexal neoplasms, molluscum contagiosum, hemangioma, basal cell carcinoma, amelanotic melanoma, and lymphomas.

These present as a well-defined hypoechoic dermal nodule, with thin low-velocity arterial vascularity (maximum peak systolic velocity, 6.5 cm/s) detected internally on color Doppler ultrasonography.

The most common presentation of breast cancer cutaneous metastasis is an asymptomatic, skin-colored, or pink-brown nodule located on the chest wall or abdomen which might also occur on the extremities. A wide spectrum of clinical presentations has been described in cutaneous breast cancer metastases, which might mimic a wide variety of benign skin lesions, such as acral fibrokeratoma, pyogenic granuloma, follicular cysts, dermatofibromas or hemangioma, included in the differential diagnosis of adult xanthogranuloma.
