Mimics of pilomatrixomas in fine-needle aspirates.

This is a review of the fine-needle aspirates (FNAs) of nine pilomatrixomas (PMs) found in a series of 1,500 FNAs performed on skin nodules. The objective is to determine and list the cytologic findings that might mislead the less-experienced cytopathologist and to give him advice on how to avoid such errors. The following recommendations are made: 1) The FNAs should be carried out and the smears interpreted by the same person. 2) Clinical data, particularly age and location, are of paramount importance. 3) Shadow cells are pathognomonic of PMs. 4) Basaloid nuclei with prominent nucleoli should not be overdiagnosed. 5) Use both Papanicolaou and Diff-Quik stains. 6) Think of PM when performing and interpreting aspirations from subcutaneous growths located in the head and neck of young persons.

[Cystic adenoid carcinoma. Review of last five years in our ENT department (1987-1991)].

We present 4 cases of adenoid cystic carcinoma from different locations (parotid, submaxillary, larynx and auditory duct) and we underline the supraglottic origin of one of them. We point out the good clinical behaviour of this carcinoma, with a long tested survival, more than 5 years, in 2 of our cases. All of them showed morphological features independently of the sitting.

Merkel cell tumor of the eyelid and the cytologic aspect in fine-needle aspirates: report of a case.

We describe one case of Merkel cell tumor (MCT) of the eyelid diagnosed by fine-needle aspiration (FNA). The main cytologic features were: isolated cells, loose cohesive sheets, and rosette-like structures in a hematic background. The cells were round to ovoid and very uniform. Chromatin was finely granular and frequent mitotic figures were observed. Under close scrutiny small faintly stained juxtanuclear "caps" were seen. A strong dot-like positivity for CK22 and NFP was observed in the position corresponding to the "caps." NSE positivity was diffuse, although a weak dot-like positivity was seen in some cells. S-100 was negative. Both the cytologic features and the immunocytologic profile of Merkel cell tumor are very characteristic. FNA enables an early and confident diagnosis of this aggressive tumor and an early planning of surgery.

[Nasal angiofibroma in an adult].

We have studied a nasal Angiofibroma in a 71-years-old male, who had not undergone any male-hormonal-therapy. The age of occurrence and the clinical course of this case made the tumor very unlikely to be a silent puberal nasal angiofibroma. After morphologic exam and exclusion of other bleeding entities of the nasal cavity we arrived at the diagnosis of nasal angiofibroma. We believe that this tumor might be arisen "ex novo" and that the nasal angiofibroma of elderly people might be a new entity.

[Nasosinusal aspergillosis].

The paper reports about a bilateral maxillary sinusitis and a right pansinusitis of this unusual disease. The allergic polyposis present in the second case is probably due to fungus sensitization (as Katzenstein's case). None of them have had dental problems, not even foreign bodies inside of the sinuses (quoted from other AA.). The diagnosis must be confirmed by both the pathologist and the bacteriologist. The treatment is surgery plus antifungal drugs.

[Laryngeal sarcomatoid carcinoma: clinical, histological and immunohistochemical study of four cases].

The purpose of this study was to confirm how the use of immunohistochemical techniques can help to differentiate between tumors with a mixed proliferative pattern (epithelial and mesenchymal). It is fundamental to differentiating tumors of these characteristics in order to determine the prognosis and plan treatment. We used different techniques on tissue samples from four cases diagnosed as laryngeal sarcomatoid carcinoma. The results demonstrated that all four were sarcomatoid carcinomas, which correlated with the patients' favorable clinical evolution. The immunohistochemical study was useful for differentiating tumor type in the case of a biopsy specimen obtained from a mixed-pattern neoplasm.
