Differential Diagnosis for a 34-year-old with Acne and Swollen Glands
- Single most likely diagnosis:
- Acne vulgaris with associated lymphadenopathy: This is the most common skin condition that can cause acne and swollen glands, especially in young adults. The presence of acne and swollen lymph nodes in the neck can be a normal response to the infection and inflammation caused by acne.
- Other Likely diagnoses:
- Rosacea: A chronic skin condition characterized by inflammation, redness, and acne-like symptoms. It can also cause swollen lymph nodes, especially if there is a significant inflammatory component.
- Folliculitis: An inflammatory condition of the hair follicles, which can cause acne-like symptoms, swollen glands, and lymphadenopathy.
- Staphylococcal or streptococcal infections: Bacterial infections of the skin can cause acne-like symptoms, swollen lymph nodes, and systemic symptoms like fever.
- Do Not Miss diagnoses:
- Lymphoma: Although rare, lymphoma can present with swollen lymph nodes, skin lesions, and systemic symptoms. It is crucial to consider this diagnosis to avoid delayed diagnosis and treatment.
- Tuberculosis: A chronic bacterial infection that can cause swollen lymph nodes, skin lesions, and systemic symptoms. It is essential to consider this diagnosis, especially if the patient has a history of exposure or travel to endemic areas.
- Sarcoidosis: A systemic granulomatous disease that can cause skin lesions, swollen lymph nodes, and systemic symptoms. It is crucial to consider this diagnosis to avoid delayed diagnosis and treatment.
- Rare diagnoses:
- Lupus: A chronic autoimmune disease that can cause skin lesions, swollen lymph nodes, and systemic symptoms. Although rare, it is essential to consider this diagnosis to avoid delayed diagnosis and treatment.
- Syphilis: A chronic bacterial infection that can cause skin lesions, swollen lymph nodes, and systemic symptoms. It is crucial to consider this diagnosis, especially if the patient has a history of high-risk behavior.
- Histoplasmosis: A fungal infection that can cause skin lesions, swollen lymph nodes, and systemic symptoms. It is essential to consider this diagnosis, especially if the patient has a history of exposure to birds or bats.
