Encephalocraniocutaneous lipomatosis (ECCL) or Haberland syndrome is an uncommon sporadic neurocutaneous syndrome of unknown origin. The rarity and common ignorance of the condition often makes diagnosis difficult. The hallmark of this syndrome is the triad of skin, ocular and central nervous system (CNS) involvement and includes a long list of combination of conditions. Read More

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

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
