ABSTRACT
INTRODUCTION: Isolated parasitic swellings of the neck, particularly hydatid cysts, are rare, even in endemic countries. The aim of this study was to assess the epidemiological and clinical features and the diagnostic approach to head and neck hydatid disease. CASE REPORT: A 3-year-old boy was hospitalised for an isolated mass of the left side of the neck that had been gradually enlarging for one year. Neck ultrasound demonstrated a hypoechoic cystic structure on the lateral aspect of the neck, measuring 3.5cm in diameter. Histological examination of the surgical specimen confirmed the diagnosis of hydatid cyst. DISCUSSION: In endemic countries, a diagnosis of hydatid disease should be suspected in all cystic masses of the neck. Epidemiological, clinical, laboratory and radiological features can lead to a presumptive diagnosis of hydatid cyst and aspiration cytology can correct an erroneous diagnosis. Histological examination confirms the diagnosis in these unusual sites.

Desmoplastic mesothelioma is unusual variant of malignant mesothelioma. The diagnosis of desmoplastic mesothelioma represents one of the most difficult exercises in pleural pathology (with poor interobservers agreement) because of their abundant collagen with relatively low cellularity. The clinical course is often rapid with visceral metastases. Bony metastases have only rarely been noted. We report our case of desmoplastic mesothelioma with vertebral metastases. Our focus is to distinguish this entity from fibrous pleurisy and localized fibrous tumors, to explain histological and immunohistochemical features with review of the literature.

Buschke-Lowenstein tumour (BLT) is a giant condyloma acumina, which is rare entity and represents only 1% of all populace. It is a rare viral disease, essentially transmitted by sexual intercourse, characterized by a potential for malignant transformation, invasion and recurrence after treatment. We report a case of BLT associated with perinea-scrotal melanoma. This association was never described in the literature. The purpose of our case report is to discuss the clinical and pathological appearances of these two entities and to outline the recent studies of molecular biology, which can explain this association.

AIM: The aim of this paper is to discuss, through four cases, the characteristics of sinonasal hemangiopericytoma (SNHP) and its diagnostic difficulties. MATERIALS AND METHODS: Description of four recent, histologically proven cases of SNHP. Bibliographic research was conducted using the following principal key word: "sinonasal hemangiopericytoma". RESULTS: The four patients complained of non-specific rhino-sinusal symptoms. In each case, physical examination revealed a voluminous unilateral polyploïd tumour of the nasal cavities, documented by CT Scan and MRI. Each patient underwent complete tumour resection by endoscopic sinus surgery. Histological and immunohistochemical examination confirmed SNHP diagnosis, although no specific marker was constantly observed. To date, none of the patients has presented with recurrence. CONCLUSION: SNHP is of poorly specific clinical and histological presentation. This tumour is difficult to distinguish from solitary fibrous tumour (SFT), with which it is often confused. SNHP is of good prognosis, however lifelong follow-up must be observed.
