Differential Diagnosis
- Single Most Likely Diagnosis
- Anxiety disorder: The patient's extreme anxiety and health anxiety, combined with the inconsistent AI mole checker results, make it likely that her symptoms are exacerbated or entirely caused by her anxiety. The lack of other systemic symptoms, such as weight loss or fatigue, and the absence of bleeding or itching from the mole, further support this diagnosis.
- Other Likely Diagnoses
- Benign melanocytic nevus: The mole has been present for 13 years with recent changes, but the changes are minor and the mole is not bleeding or itching. The AI mole checker's inconsistent results also suggest that the mole may be benign.
- Reactive lymphadenopathy: The patient's lymph nodes are non-tender, movable, and have not grown in size, which is consistent with reactive lymphadenopathy, a common and benign condition.
- Do Not Miss Diagnoses
- Malignant Melanoma: Although the AI mole checker's results are inconsistent, it is essential to rule out malignant melanoma due to its potential severity and the patient's concern about the mole's changes. A dermatological examination and potential biopsy are necessary to confirm the diagnosis.
- Lymphoma: The presence of multiple lymph nodes, although non-tender and movable, requires consideration of lymphoma, a type of cancer that can present with lymphadenopathy.
- Tuberculosis: The patient's night sweats, although occasional, could be a symptom of tuberculosis, which can also cause lymphadenopathy.
- Rare Diagnoses
- Sarcoidosis: This rare condition can cause lymphadenopathy and skin lesions, but it is less likely given the patient's lack of other systemic symptoms.
- Leukemia: Although rare, leukemia can cause lymphadenopathy and night sweats, but it is less likely given the patient's age and lack of other symptoms, such as fatigue or weight loss.
