Differential Diagnosis for Grape Sized Movable Lump Pre-Auricular TMJ Area
- Single Most Likely Diagnosis
- Benign Parotid Gland Tumor (e.g., Pleomorphic Adenoma): This is the most likely diagnosis due to the location (pre-auricular area) and description (grape-sized movable lump) which is consistent with a benign tumor of the parotid gland, such as a pleomorphic adenoma.
- Other Likely Diagnoses
- Lipoma: A benign tumor composed of fat tissue, which can occur in the pre-auricular area and present as a movable lump.
- Cystic Lymph Node: An enlarged lymph node in the pre-auricular area can present as a movable lump, although it is less common.
- Branchial Cleft Cyst: A congenital anomaly that can present as a lump in the pre-auricular area, although it is more commonly seen in the neck.
- Do Not Miss Diagnoses
- Parotid Gland Malignancy: Although less common, a malignant tumor of the parotid gland (e.g., mucoepidermoid carcinoma, adenoid cystic carcinoma) can present similarly to a benign tumor and would have significant implications for treatment and prognosis.
- Metastatic Disease: A metastatic lesion to the parotid gland or a lymph node in the pre-auricular area, although rare, would be critical to diagnose due to its implications for overall health and treatment.
- Rare Diagnoses
- Dermoid Cyst: A congenital anomaly that can present as a lump in the pre-auricular area, although it is rare.
- Teratoma: A rare type of tumor that can occur in the pre-auricular area, composed of multiple tissue types.
- Neurofibroma: A benign tumor of the nerve tissue, which can occur in the pre-auricular area, although it is rare.
