ABSTRACT
La supervivencia de pacientes con metástasis cutánea de melanoma de origen primario desconocido, clasificados como estadio IV (M1a) por el American Joint Comittee on Cancer para melanoma, se estima en un 5-17,9% a los 5 años, con una mediana de 6 meses. Es conocida la existencia de pacientes así clasificados que presentan una supervivencia mucho mayor, lo que ha llevado a utilizar el término de «melanoma dérmico primario» (MDP). Presentamos un caso compatible con MDP, así como una revisión de los principales artículos publicados. El diagnóstico está sujeto a una correcta correlación clínico-patológica y debe ser considerado en todos los pacientes con melanoma solitario confinado en la dermis y en el tejido celular subcutáneo, en los que no se encuentre un origen primario ni evidencia de enfermedad tras un adecuado estudio de extensión. Creemos necesario el conocimiento de esta posibilidad para un correcto manejo e información pronóstica de los pacientes (AU)
Patients with cutaneous metastatic melanoma of unknown primary origin (stage IVM1a disease according to the American Joint Committee on Cancer melanoma staging system) have an estimated 5-year survival rate of between 5% and 17.9% and a median survival of 6 months. However, certain patients with stage IV M1 a disease have much higher survival rates. The existence of this subpopulation has given rise to the term primary dermal melanoma to describe such cases. We report a case of melanoma with characteristics consistent with primary dermal melanoma and review the relevant literature. A diagnosis of primary dermal melanoma requires careful clinical and pathologic correlation and should be considered in all patients with a solitary melanoma confined to the dermis and subcutaneous tissue when there is no evidence of a primary tumor or disease at other sites following appropriate staging studies. We believe that familiarity with this subtype of melanoma is essential in order to provide patients with optimal care and better prognostic information (AU)

Two patients with two and three types respectively of ground-glass hepatocyte inclusions are described. Both were hepatitis B surface antigen (HBsAG) positive and received cyanamide for alcohol aversion therapy. In addition, one of them had taken benzodiazepines and barbiturates. In one patient, cyanamide and HBsAg inclusions co-existed in the same hepatocytes.

We report herein a new case of dyshidrosiform pemphigoid. Although vesiculo-bullae on palms or soles are frequent components of bullous pemphigoid, they are rare as a presenting phenomenon. In our opinion, dyshidrosiform pemphigoid should not be regarded as a distinctive form of localized pemphigoid.

The cytopathologic features of the fine needle aspiration biopsy of a myxoid metastasis of a cutaneous malignant melanoma are documented. The cytologic findings included fusiform-to-round cells with elongated cytoplasmic processes, fibroblastlike cells and inflammatory cells in a characteristic amorphous background substance. Immunocytochemical staining for S-100 protein was positive. The cytologic findings correlated well the histologic, histochemical, immunohistochemical and ultrastructural studies of the neoplasm. The cytologic differential diagnosis between metastases of malignant melanoma and other myxoid tumors of soft tissues is discussed.
