Juvenile xanthogranulomas (JXGs) are benign, usually asymptomatic, self-healing, red-to-yellowish papules and nodules composed of histiocytic cells that predominantly occur in infancy and childhood. Papules or nodules occur in the skin, eyes, and viscera. JXG is the most common form of non–Langerhans cell histiocytosis.

The appearance of giant cells and foamy lipid-laden histiocytes generally occurs late and apparently is a secondary event, possibly in response to cytokine production by histiocytes. Serum lipid levels are normal and remain normal.

- Coexistence of café au lait macules has been associated with epilepsy.
- Niemann-Pick disease has been associated with JXG.
- Urticaria pigmentosa has been associated with JXG.
- Neurofibromatosis type 1 (NF1) has been associated with JXG. A retrospective study has estimated that as many as 1 in 5 children with NF1 before age 3 years will develop JXG.
- Juvenile chronic myelogenous leukemia, now primarily referred to as juvenile myelomonocytic leukemia (JMML), has been observed in association with multiple JXGs, and the prevalence is especially high in patients with coexistent neurofibromatosis.

Well in PCOD we have Inc Production Of LH so the Theca cells shud be Hypertrophic while i think Granulosa cells will be hypertrphic too.??

look Theca Cells r stimulated by LH right
In PCOS We Have Inc LH n Dec FSH theca cells will hypertrophied Granulosa Cells r under the influence of LH n FSH both (i.e They have receptors for both) so they will also be hypertrophied right
