Distinct presentations of scalp dissecting cellulitis manifesting with furrows and gyri.

Dissecting cellulitis (DC) is a neutrophilic scarring alopecia characterized by papules, pustules, nodules, and abscesses mainly in the vertex and occipital areas of the scalp.[[1]] In some cases of scalp DC, folds and furrows may co-occur or be misdiagnosed with Cutis Verticis Gyrata (CVG). The patient had CVG and developed DC overtime. gl Cutis Verticis Gyrata is a progressive scalp thickening deformity characterized by the presence of skin folds and deep furrows, resembling the convoluted appearance of the brain. We aim to describe four distinct presentations of scalp DC that present with furrows and gyri: cicatricial areas of late-stage DC mimicking CVG, an association of primary CVG and DC, Jacquet's sign, and scalp hypermobility.
