Pilomatrix carcinoma is an uncommon malignant neoplasm originating from the hair follicle matrix. It occurs more frequently in head and neck region and rarely on the eyelid and eyebrow. It is often clinically misdiagnosed. The diagnosis is confirmed by excision biopsy and histopathological examination. A 68-year-old woman presented with a mass on her left eyebrow mimicking sebaceous cyst. An excisional biopsy with 4-mm margin was performed under frozen section. Histopathology demonstrated pilomatrix carcinoma with cystic degeneration. Periocular malignancies can have unusual origins with specific clinical features. Preoperative clinical examination is mandatory to rule out unusual features and thereby ensure appropriate management to prevent serious complications.

Dirofilariasis is a zoonotic infection caused by filarial nematodes belonging to the genus dirofilariae. Dirofilaria is commonly seen in dogs, cats and other carnivorous animals world wide. Mosquitoes of the genus Culex, Anopheles and Aedes are the vectors and the humans are either incidental hosts or dead-end hosts. It affects lungs, liver and other visceral organs. Ocular involvement is rarely been reported. We present a case of 51-year-old female from Kerala, the southern State of India presented with a mass mimicking lacrimal sac mucocoele whose biopsy is proved to be dirofilariasis.
