Malignant proliferating trichilemmal tumour of the scalp. Report of a case and a short review of the literature.

Background: Malignant proliferating trichilemmal tumour is a rare skin tumour that originates from the root sheath of the hair and usually arises in the sun-exposed areas of elderly women. It mimicks poorly differential squamous cell carcinoma ant its biological behaviour is unpredictable, because rarely can produce distant metastases.

Case Report: The Authors report on a case of a 54-year-old female patients who proceeded with a cystic lesion in the scalp.

Adamantinoma of tibia: a case of late local recurrence along with lung metastases.

Adamantinomas of long bones are rare primary low-grade malignant tumours composed of cells with epithelial and fibrous characteristics. Local recurrence, though scarce, occurs 5-15 years after the onset of diagnosis. We report a case of local recurrence of an adamantinoma localised in tibia, along with the presence of two lung metastases, 24 years after diagnosis and surgical therapy of the primary tumour.
