Free anterolateral thigh flap for reconstruction of complex craniofacial defects after resection of tumors of the fronto-orbitomaxillary complex.

Tumors of the fronto-orbitomaxillary segment are complex and pose a significant challenge for radical resection and subsequent reconstruction. With evolution in surgical reconstructive techniques, better reconstruction of these complex defects is now possible and facilitates more aggressive surgical management. The anterolateral thigh (ALT) flap has features particularly suited for this reconstruction.

Masquerade syndrome: sebaceous carcinoma presenting as an unknown primary with pagetoid spread to the nasal cavity.

Sebaceous carcinoma of the eyelid is an uncommon tumour with unusual modes of presentation. It can remain occult at the primary site, without producing any mass, masquerading as chronic blepharoconjunctivitis, while setting up metastases in the regional lymph nodes especially in the pre-auricular group. We report here a case that not only masqueraded as chronic blepharoconjunctivitis with nodal metastases from an 'unknown primary' in the neck, but whose tumour spread in a pagetoid manner along the nasolacrimal duct producing a nasal tumour that was believed to be the 'unknown primary'.
