Myiasis on a Giant Squamous Cell Carcinoma of the Scalp: A Case Report and Review of Relevant Literature.

Non-melanoma skin cancer is the most common malignancy amongst Caucasians worldwide with basal cell and squamous cell cancer being the most common. Giant skin cancers are a relatively rare type of skin cancer that are, by definition, greater than 5 cm. This subtype by itself is associated with a significantly increased risk of complications and mortality. Myiasis is defined as infestation of body tissues of humans by dipterous larvae. Myiasis is often associated with malignant skin conditions. We describe a rare case of cutaneous myiasis located on a giant squamous cell carcinoma of the scalp in an elderly female. Myiasis coupled with malignant skin conditions provides a unique surgical challenge. This is especially true if the malignancy is invasive, as in our case, often requiring a multidisciplinary multimodality treatment plan.
