Diffuse cutaneous mastocytosis

Although blistering can occur in any form but is characteristic of the diffuse cutaneous variety also known as bullous mastocytosis and is one of the important entities that needs to be differentiated from the other bullous disorder of infancy. The CM can occur at any age and demonstrates a slight male-to-female predominance (1.5:1.0) Diffuse cutaneous mastocytosis (DCM) is a rare form of cutaneous mastocytosis (CM; see this term) characterized by generalized erythroderma, various degrees of blistering, skin with a ''peau d'orange'' appearance and the accumulation of mast cells in the skin. At least two DCM variants are recognized, one with extreme blistering (Bullous DCM; see this term) and one with infiltrations. A variant of cutaneous mastocytosis which is seen almost exclusively in children. (WHO, 2001 Diffuse Cutaneous Mastocytosis (DCM) is a very rare form of the condition that presents at birth with skin that is thickened and easily blistered. A mastocytoma is a raised nodule that is also usually seen in infancy Diffuse cutaneous mastocytosis (DCM) is seen in children and is the most severe form of cutaneous mastocytosis.

While cutaneous mastocytosis can include maculopapular cutaneous mastocytosis (MPCM), formerly known as urticaria pigmentosa (UP), telangiectasia macularis eruptiva perstans (TMEP), diffuse cutaneous mastocytosis (DCM), and cutaneous mastocytoma, skin manifestations can also occur in systemic mastocytosis (SM), mast cell activation syndrome.

The last presentation involves diffuse cutaneous involvement. Urticaria pigmentosa is the most common cutaneous mastocytosis in children, and it can form in adults as well. It is thought to be a benign, self-resolving condition that remits in adolescence. Unlike adult forms of mastocytosis, there is rarely any internal organ involvement in UP.

The skin is the most frequently affected organ, followed by bone marrow. Cutaneous mast cell infiltration is usually associated with typical skin lesions. According to the morphology of the lesions, three subforms are distinguished, namely maculopapular cutaneous mastocytosis, diffuse cutaneous mastocytosis and cutaneous mastocytoma Urticaria pigmentosa occurs when there are too many inflammatory cells (mast cells) in the skin. Mast cells are immune system cells that help the body fight infections. Mast cells make and release histamine, which causes nearby tissues to become swollen and inflamed. Urticaria pigmentosa is most common in children
