Myiasis in a Skull Metastatic Nest of Cervical Cancer
ABSTRACT
We report a case of semispecific myiasis in a cutaneous skull metastasis of cervical cancer. A 43‐year‐old woman developed larval infestation in an ulcerated occipital lesion. Fifty‐two larvae were morphologically identified as
Lucilia sericata
. To control myiasis, we removed larvae by hand and applied petrolatum with topical zinc oxide starch powder. The ulcer surface improved, and no recurrence of myiasis was observed. Myiasis typically occurs in individuals with necrotic wounds, poor hygiene, or immunosuppression. This is the first report of myiasis occurring in a metastatic lesion of cervical cancer. We reviewed 36 cases of facultative myiasis in Japan since 2010, highlighting risk factors such as old age, dementia, malignancy, and solitary living.
L. sericata
was one of the most frequently identified species. Topical zinc oxide starch powder proved effective, offering a simple, noninvasive treatment option. This case expands the clinical spectrum of myiasis and suggests that zinc oxide starch powder may be useful in palliative wound care for advanced cancer patients.
