Cylindromas are benign tumours arising as small, solitary, slow-growing nodules on the head and neck. Multiple cylindromas may form a 'turban tumour' in the autosomal dominant Brooke-Spiegler syndrome. We report two unusual cases of multiple cylindromas with transformation into cylindrocarcinomas. The first patient, a 63-year-old white woman, developed a cylindrocarcinoma on pre-existing multiple cylindromas on her right shoulder. Eight months after resection she developed a lymph node metastasis in the right axilla. The second patient, a 68-year-old white woman, presented with multiple cylindromas of the scalp. One of these transformed into a cylindrocarcinoma, infiltrating the dura mater, with local recurrence 2 years after incomplete resection and postoperative radiation.

These data confirm that scintigraphy with the radiolabelled somatostatin analogue octreotide is not clinically helpful in detecting metastases from Merkel cell carcinoma. In this relatively small sample the method generated false-positive or false-negative results in five of 11 cases.

Sweet's syndrome was first described in 1964. It is characterized by an acute onset of non-pruritic, painful reddish nodules on the head and neck, chest and/or the upper limbs, mostly accompanied by fever, general malaise and leucocytosis. Histopathological examination shows a diffuse dermal neutrophilic infiltrate. The pathogenesis is still not fully understood, and different diseases have been shown to be associated with this syndrome. However, although still very rare, there is an increase of reports on Sweet's syndrome induced by drugs. We describe a 30-year-old man who experienced acute neutrophilic dermatosis after systemic treatment with minocycline. Additionally, there is a strong possibility that the same patient developed a drug-induced Sweet's syndrome after oral administration of tetracycline and doxycycline.

Epifocal DNCB combined with DTIC is effective in patients with regionally metastasized melanoma not amenable to surgery or isolated limb perfusion, whereas in stage IV disease in spite of few durable remissions the addition of DNCB does not improve the therapeutic efficacy of DTIC.
