This is a case report of a Pott's puffy tumor, characterized by a subperiosteal abscess associated with frontal bone osteomyelitis, as a consequence of a frontal sinusitis, in a 15-year-old boy. Pott's puffy tumor is a rare condition usually seen as a complication of frontal sinusitis and more commonly described in children. Given that, superficial temporal artery pseudoaneurysms might be interpreted as a cyst or lipoma, it is imperative that physicians be aware of their presentation.

Localized bullous pemphigoid (LBP) rarely evolves into the generalized form, and the prognosis is better. In our opinion, the occurrence of LBP is underestimated because of incorrect diagnoses. It is therefore important to perform a skin biopsy each time a bullous rash is concerned in order to make a definite diagnosis.
