    Occurrence of dermoid cyst in the floor of the mouth: the importance of differential diagnosis in pediatric patients.
    J Appl Oral Sci 2017 May-Jun;25(3):341-345
    Universidade Federal do Rio Grande do Sul, Faculdade de Odontologia; Hospital de Clínicas de Porto Alegre, Unidade de Cirurgia Buco-maxilo-facial, Porto Alegre, RS, Brasil.
    Lesions in the floor of the mouth can be a challenging diagnosis due to the variety of pathological conditions that might be found in this area. Within a broad range of lesions, attention has to be addressed to those that require specific management, such as a dermoid cyst (DC) and a ranula. Especially in pediatric patients, in whom the failure of diagnosis can postpone the correct treatment and cause sequelae later in life. Read More

    Pediatr Dermatol 2017 May 27;34(3):e135-e136. Epub 2017 Feb 27.
    Division of Pediatric Dermatology, Nationwide Children's Hospital and Ohio State University Medical Center, Columbus, Ohio.
    Intramuscular lipomas are rare, benign, mesenchymal tumors occurring deep in the fascia, typically involving large muscle groups in adults. We report a case of an intramuscular lipoma occurring as a subcutaneous midline nasal mass in a 3-month-old infant. The differential diagnosis of a midline mass on the glabella of an infant is important and should include developmental anomalies such as nasal glioma, nasal dermoid cyst, and encephalocele, so neuroimaging is an essential first step in evaluating these lesions to exclude intracranial extension.

    Mature Cystic Teratoma with Co-existent Mucinous Cystadenocarcinoma in the same Ovary-A Diagnostic Dilemma.
    J Clin Diagn Res 2016 Dec 1;10(12):ED11-ED13. Epub 2016 Dec 1.
    Associate Professor, Department of Diagnostic Radiology and Imaging, Chrisitan Medical College , Vellore, Tamil Nadu, India .
    Mature cystic teratoma co-existing with a mucinous cystadenocarcinoma is an infrequently encountered entity with only a handful of cases reported till date. The possibilities in such a case are either a malignant transformation of a benign teratoma into adenocarcinoma or a collision tumor between a mature cystic teratoma and a mucinous tumour of either a primary ovarian surface epithelial-stromal origin or a secondary from a primary gastrointestinal tract tumour. The importance of distinguishing between the two entities has significant bearing on subsequent therapeutic management. Read More
