We discuss six dog eponyms related to dermatology: Bulldog scalp syndrome (cutis verticis gyrata), Bulldog nose, Bulldog face (facies), Bulldog jaw, dog ears, and canine teeth (Fournier's canines). This collection of eponyms is dedicated to dogs, who have contributed to advancing medicine and public health.

Lipedematous scalp (LS) and lipedematous alopecia (LA) are rare conditions involving focal or diffuse hyperplasia within subcutaneous adipose tissue of the scalp. Little is known regarding the etiology of these conditions, and there is no consensus on management strategies. Overall, the condition is benign and often isolated. However, there have been reported cases of co-existing scalp edema in the presence of another pathogenic process involving the scalp and hair. The authors present a case of significant scalp edema in a middle-aged female who presented with lichen planopilaris (LPP) of the bifrontal scalp of four years duration. The patient had diffuse thinning of the frontal scalp with a perifollicular scale, and further examination revealed significant edema and bogginess of the remainder of the scalp. A punch biopsy of the frontal scalp was obtained and consistent with LPP. LA is typically seen in areas where both scalp thickening and hair loss are present and has little or no histologic inflammation. This case highlights the presence of scalp edema in a patient with inflammatory scarring hair loss, which has not been previously reported. This may suggest a new variant of this spectrum of hyperplastic or edematous conditions of the scalp as a reactive process in the presence of another primary, inciting condition such as scarring alopecia. Additionally, LA should be a diagnosis of exclusion after ruling out treatable alopecic conditions such as LPP.

Lipedematous scalp is a rare cutaneous disorder, characterized by subtle but conspicuous scalp swelling, usually associated with dysesthesia. The chronic recalcitrant nature of this condition can be extremely debilitating for the patient. We report a case of boggy scalp swelling and dysesthesia in a 37‑year‑old female present for five years. Magnetic resonance imaging (MRI) brain showed thickening of subcutaneous tissue of the scalp. Histopathological examination revealed thickened and edematous subcutaneous tissue, reaching up to the upper dermis. A diagnosis of lipedematous scalp was made. The patient was reassured about the benign nature of the disease and given symptomatic treatment for dysesthesia. Herein we discuss the approach to a case of boggy dysesthetic scalp swelling and the available treatment options.
