Basaloid-squamous carcinoma of larynx metastatic to the skin of the nasal tip.

Basaloid-squamous carcinoma is a rare, highly malignant epithelial tumour with problematic histological characteristics and a poor prognosis. This unusual tumour has been described in the tongue, hypopharynx, and larynx. A unique case of basaloid-squamous carcinoma of the larynx metastatic to the skin of the nasal tip is presented. The literature regarding the histopathological and clinical aspects of basaloid-squamous carcinoma is reviewed.

Fatal aspiration pneumonia caused by an esophageal foreign body.

Esophageal foreign body accompanied by respiratory complications is a rare condition. A few cases have been reported, only two of them in adults. We describe the case of a 34-year-old mentally retarded patient who was hospitalized for aspiration pneumonia and died 48 hours after admission. At autopsy, the prominent finding was a 3 X 3-cm stone impacted into the upper esophagus and compressing the trachea from behind. The possibility of an esophageal foreign body should be included in the differential diagnosis of unexplained respiratory distress or aspiration pneumonia in adults.

Diagnostic use of the immunoperoxidase technique for cutaneous plasma cell lesions.

Distinguishing cutaneous neoplastic plasma cell infiltrations from inflammatory reactions containing predominantly plasma cells can present diagnostic problems when conventional histological techniques are used. Eight cases of cutaneous lesions, composed almost exclusively of plasma cells, are presented. We discuss the use of the peroxidase-antiperoxidase technique to distinguish malignant plasma cells that produce only one type of immunoglobulin from benign lesions that are polyclonal and produce several immunoglobulins.
