Metastatic squamous cell carcinoma in a liver graft. Report of a case diagnosed by fine needle aspiration.

BACKGROUND: Fine needle aspiration is a well-established and safe method for the diagnosis of focal liver lesions, but it has played a limited role in the transplant setting. CASE: A case of metastatic squamous cell carcinoma in a liver graft was diagnosed by fine needle aspiration. The tumor developed in the right pyriform sinus five years after an orthotopic liver transplantation was performed. CONCLUSION: With the improvement of survival rates following liver transplantation, metastatic tumors should be considered in liver grafts with space-occupying lesions. Therefore, fine needle aspiration is adequate for diagnosis and is cost-effective and safe.

Subareolar abscess of the breast in a male. A report of two cases with fine needle aspiration cytology diagnosis.

BACKGROUND: Fine needle aspiration (FNA) is a well-established method for the diagnosis of breast diseases in males, but very little attention has been focused on inflammatory lesions. Previous reports do not mention subareolar abscess (SA), which is a distinct entity in breasts of females. CASES: Two adult males presented for FNA of recurrent breast masses located near the nipple. Smears from both patients showed the typical cytologic features of SA. CONCLUSION: Recognition of this troublesome and rare condition on FNA cytology from the breasts in males will prevent recurrences since SA is not cured by excisional biopsy.

Primary cardiac hydatid cyst in a child. Cytologic diagnosis of a case.

BACKGROUND: Echinococcosis is a troublesome disease, particularly common in sheep-raising communities and usually caused by the cestode Echinococcus granulosus. Although it has been found in almost every organ, isolated cardiac disease is an exceptional presentation since cardiac involvement occurs in only 0.5-3% of echinococcosis cases. CASE: A case of primary cardiac hydatid cyst occurred in a 4-year-old male. The asymptomatic patient was admitted to the hospital for evaluation of an intracardiac cyst. The lesion was successfully excised by open heart surgery, and a definitive diagnosis was made postoperatively by Giemsa staining of hooklets and scolices in cyst fluid. CONCLUSION: This case is of special interest because of the rare site of the lesion and young age of the patient. Pathologists should be alert to the possibility of this parasite appearing in unusual clinical settings.
