Abstract
Merkel Cell Carcinoma (MCC) is a rare aggressive tumor known to be
metastatic to the lymph nodes with a poor prognosis. It is commonly characterized
as a painless rapidly enlarging papule or nodule, which may be skin-colored,
erythematous to violaceous. Being twice as uncommon as melanoma, it is seen
among Caucasian elderly males. A case of a 65-year-old male, known hypertensive
with chronic kidney disease, with a sudden enlargement of a painless nodule (2 x
2 x 1 cm) over the left temple is presented in this report. Initial histopathologic
finding was lymphoma, however due to its rapid enlargement further work-up
with imnunohistochemical stains done confirmed the diagnosis of MCC. The
development of MCC in a Filipino is rare and its detection requires a high index
of suspicion. Upon referral to plastic surgery and radiation oncology, wide local
excision and adjuvant radiotherapy were advised respectively. A wide local excision
with margin control and subsequent skin-grafting was done. Thirty-three sessions
of radiotherapy was advised however patient refused the suggested adjuvant
treatment. Absence of nodal involvement and metastasis were documented with
CT scan of the head, neck and abdomen showing no signs of adenopathy
