Multiple Trichilemmal Cysts of the Scalp

Different entities can be the cause of scalp neoplasia. In a phenotype with multiple cystic scalp lesions, the diagnosis must be made with particular caution because the appearance of apparently benign tumors does not necessarily correspond to the biological behaviour of the lesions. This case report describes diagnosis and therapy of a patient with multiple cystic tumors confined to the scalp. Diagnosis of benign lesions all over the scalp allowed an aesthetically pleasing surgical treatment result. Long-term follow-up control was offered to the patient because the histological diagnosis identified further small tumors of the same type as the large lesions, so further neoplasms are likely to develop.
