Juvenile xanthogranuloma (JXG) is a benign, non-Langerhans cell histiocytosis, which commonly manifests as a solitary papule or nodule in infants and young children. However, other less common clinical presentations have been reported including clustered, agminated or plaque-like. It is important to recognize these variants, as diagnosis is often clinical. We highlight a case of juvenile xanthogranuloma presenting as nodules on the trunk of an infant that gradually coalesced to form a larger plaque.

Both, generalized eruptive histiocytosis and juvenile xanthogranuloma are dendritic histiocytic disorders (also known as non-Langerhans cells histiocytosis) that share clinicopathological and immunohistiochemical characteristics. We present a 3-year-old female patient with skin lesions that were clinically compatible with generalized eruptive histiocytosis, confirmed by histopathological and immunohistochemical studies. During her development the disorder compromised the central nervous system, and surgical intervention of one symptomatic lesion was needed...

BACKGROUND/OBJECTIVES: Mosaic neurofibromatosis type 1 (MNF1) is a variant of neurofibromatosis type 1 (NF1) in which clinical manifestations are limited to one or several body segments. The objective was to characterize the cutaneous features and associated systemic findings in a cohort of children with MNF1. METHODS: We performed a retrospective study of 40 children diagnosed with MNF1 at the Department of Dermatology, Hospital Infantil Niño Jesús, Madrid, Spain, from January 1, 1986, to October 31, 2015...

Juvenile xanthogranuloma (JXG) is the most frequent form of non-Langerhans cell histiocytosis. We present a case of giant congenital JXG in a 7-week-old boy, who had a firm and incompressible lesion, measuring 3 × 4 cm in diameter, on his right flank. The clinical appearance of the lesion and the ultrasound results suggested a vascular tumor, such as a hemangioma. Histology confirmed a JXG, although there was an absence of Touton cells, which are usually pathognomonic of JXG. In light of these findings, it would be important to include JXG in the differential diagnosis of congenital tumours, particularly vascular lesions...

A patient with overlap between juvenile xanthogranuloma and progressive nodular histiocytosis is presented. He had progressive, superficial, small, yellow-reddish papules and large dermal nodules, consistent with progressive nodular histiocytosis. Histopathology showed distinctive features of juvenile xanthogranuloma. Our patient reinforces the view that progressive nodular histiocytosis is not a distinct clinical entity, but an evolutionary form of juvenile xanthogranuloma.

We report two cases of patients with necrobiotic xanthogranuloma (NXG) associated with monoclonal gammopathy. Besides cutaneous lesions, they both presented idiopathic non-cirrhotic portal hypertension (INCPH). In 2007, a 65-year-old woman was referred for nodular eruption (Fig. 1 - A) located around the neck. Cervical skin biopsy showed normal epidermis and a layer of inflammatory elements on the reticular dermis. This article is protected by copyright. All rights reserved.

The sellar xanthogranuloma is a rare lesion of the sellar-parasellar region difficult to differentiate from other tumors such as craniopharyngiomas or Rathke's cleft cyst in the preoperative evaluation. As they are recently recognized as a separate entity and the few number of reports in the literature, its etiology is unknown and its impact remains uncertain. This article will describe the first three cases reported in Latin America, identified in one of them an imaging feature that may be helpful to elucidate an imaging growth pattern...

Adult xanthogranulomatous disease of the orbit refers to a heterogeneous group of clinical syndromes with differing degrees of systemic involvement and distinct prognoses. The different syndromes all present clinically with progressively enlarging, yellowish lesions of the orbit. Histologically, the lesions are characterized by an inflammatory infiltrate of foam cells and Touton-type multinucleated giant cells. The xanthomatized histiocytes are CD68(+), S100(-), and CD1a(-). There are 4 clinical forms of xanthogranulomatous disease of the orbit: adult xanthogranulomatous disease of the orbit, adult onset asthma and periocular xanthogranuloma, necrobiotic xanthogranuloma, and Erdheim-Chester disease...

Xanthomatous lesions of the sellar region have traditionally been divided into two separate categories, xanthomatous hypophysitis (XH) and xanthogranuloma (XG) of the sellar region. The seminal paper on XH, a condition typified by foamy histiocytes and lymphoplasmacytic infiltrates in the pituitary gland/sellar region, but usually little or no hemosiderin pigment, detailed 3 patients. However, most reports since that time have been single cases, making understanding of the entity difficult. In contrast, the seminal report on XG, characterized by sellar region cholesterol clefts, lymphoplasmacytic infiltrates, marked hemosiderin deposits, fibrosis, multinucleated giant cells around cholesterol clefts, eosinophilic granular necrotic debris, and accumulation of macrophages, included 37 patients, allowing more insights into etiology...

The occurrence of juvenile myelomonocytic leukemia (JMML), juvenile xanthogranuloma (JXG), and neurofibromatosis type 1 (NF1) together is relatively rare. Approximately only 20 cases have been reported in the literature. It is debated whether children with NF1 and JXG are at higher risk of developing JMML than children with NF1 alone. We present the case of a boy primarily diagnosed with NF1 with coexisting JXG who developed JMML at the age of 22 months. The clinical course from initial presentation to final diagnosis is detailed and the genetic features and hematologic characteristics are discussed...

An 82-year-old woman presented with a 9-month history of multiple, well-defined skin lesions on her neck and upper chest, progressively increasing in size. Histological examination of a skin biopsy showed a regular epidermis. In the dermis, granulomatous changes with central necrobiosis were found which extended focally into the subcutaneous fat. The necrobiotic areas were surrounded by Touton cells and foreign-body giant cells. Laboratory analysis revealed leucopenia. Serum electrophoresis and immunofixation disclosed the presence of an IgG-λ paraprotein...

Juvenile xanthogranuloma is a bening pathology and it represents the most common form of non-Langerhans cell histiocytosis. It is characterized by the presence of papules or firm nodules of a pinkish or yellow-brownish nature, which mainly compromise the skin and, exceptionally, other organs. It is a self-limited entity having a spontaneous regression during the first five years of life. We report the case of a one-month-old patient who presented a congenital tumor in the abdomen, whose histopathology showed the presence of multinucleated giant Touton cells, which are typical of this pathology...

OBJECTIVE: Xanthogranulomatous (XG) processes are rare inflammatory conditions with the characteristic pathologic feature of lipid-laden macrophages or histiocyte cells. Imaging findings are nonspecific and can simulate aggressive neoplastic processes. XG processes can be caused by infection, inflammation, histolytic process, or an inherited lysosomal disorder. XG infectious processes are mainly seen in cholecystitis and pyelonephritis, but several other organs can also be involved. Histiocytic processes can be divided into Langerhans and non-Langerhans cell histiocytosis...

A 10-year-old child presented with asymptomatic, well-circumscribed nodule in the vulva. Excision biopsy showed features of classic Juvenile Xanthogranuloma (JXG) which is a rare benign disorder of non-langerhans' cell group of histiocytic proliferative diseases. The presentation of this lesion as vulval nodule is extremely rare and the extensive literature search revealed only handful of cases of vulval xanthogranuloma that too in an adult age group. The lesion is however prognostically favourable and should be kept in mind as one of the differential diagnosis of the vulval nodule...

Xanthogranuloma is a benign, non-Langerhans cell histiocytosis primarily diagnosed in infants and children, although a subset occurs in adults. Multifocal eruptive presentation of xanthogranuloma is very rare with only 4 previous cases reported in the literature to our knowledge. We describe a case of eruptive xanthogranuloma in a 49-year-old man who presented with sudden onset of numerous asymptomatic, red-yellow to orange papules on the face, scalp, axilla, flank and scrotum. Histologic features were consistent with xanthogranuloma with diffuse mixed infiltrate of foamy histiocytes, Touton giant cells and lymphocytes...

BACKGROUND: Xanthogranulomas are uncommon granulomatous entities, and xanthogranulomas occurring in the sellar region are extremely rare, with a limited number of cases reported in the literature. Diagnosis, management, and prognosis of sellar xanthogranulomas are poorly understood. METHODS: We retrospectively reviewed 14 patients with histologically proven sellar xanthogranulomas treated at our institution between January 2006 and July 2016. Clinical manifestations, radiologic features, operative records, and follow-up outcomes were analyzed...
