Cutaneous metastases are infrequent and in some cases represent the first manifestation of an unknown neoplasm. Acrally located metastases are particularly rare, and the prognosis is very poor, with a survival time of only a few months. Although the clinical presentation varies, they are generally confused with an infectious or inflammatory process, which delays diagnosis. When they are located on the fingers, the most frequent cause is lung carcinoma, while those located on the toes are usually due to tumors in the genitourinary tract. The histology of the metastasis is similar to that of the primary tumor, although less differentiated. In most acrometastases, first the bone and then the skin are affected. Treatment is palliative. We present the case of a patient with a metastasis on the big toe as an initial sign of a previously unknown lung tumor.

Epithelioid hemangioendothelioma is a rare vascular tumor of intermediate aggressiveness, which usually appears in adults. It generally affects soft tissues and, less frequently, the lungs and liver. Diagnosis is by histological evaluation, and the epithelioid appearance of the neoplastic endothelial cells is typical, as is the tendency to form vascular channels. Treatment is surgical excision, with broad margins. This tumor may in exceptional cases affect the skin, with few cases having been described in literature. We describe the case of a male patient with plantar epithelioid hemangioendothelioma, and we review the literature.

Superficial angiomyxomas are clinically variable, infrequent, benign skin lesions. They are usually located on the trunk, but can also appear on the lower limbs, head and neck. They are diagnosed histologically, and are characterized by the fact that they are poorly delimited, multinodular tumors, and by the presence of interstitial myxoid material with scanty cellularity. Treatment is through surgery, and local recurrence is possible. An associated Carney's complex must always be ruled out with superficial angiomyxoma. We present the case of a woman with a solitary, fast-growing superficial angiomyxoma.

Diffuse normolipemic plane xanthomas are characterized by the presence of yellowish plaques on the eyelids, neck, upper trunk, buttocks and flexures. Histology shows foamy histiocytes in the dermis. Approximately half of all cases are associated with hematological disorders. On rare occasions, they have been described in the context of cutaneous T-cell lymphomas. We present the case of a female patient with tumor-stage mycosis fungoides who developed normolipemic plane xanthomas coinciding with the appearance of new lymphoma lesions. We review English-language literature regarding the rare association of xanthomas and cutaneous T-cell lymphomas.

Panniculitic T-cell lymphoma is a rare, aggressive variant of cutaneous T-cell lymphoma, with fewer than 100 cases described. The main problem is its diagnosis, as both the clinical and the histological features may simulate benign panniculitis. We present the case of a 34-year-old male patient, who had presented with an indurated plaque, sclerodermiform in appearance, on the front of the right thigh for 4 months, later accompanied by fever and constitutional symptoms. The initial diagnosis was cellulitis, but no clinical improvement was seen despite systemic antibiotic therapy. After two skin biopsies, the patient was diagnosed with panniculitic cutaneous T-cell lymphoma. The patient was treated with 8 cycles of CHOP chemotherapy, with resolution of the symptoms.

The authors present a study on the cementum of impacted teeth. It was not possible to correlate the thickness of the cementum and the age of the patients. Significant differences were found, on the other hand, between the thickness and distribution of the cementum in different teeth. Third molars showed in almost all cases an increase in the thickness of cementum.
