The types of tests that are needed for Poroma include:
1. Visual examination of the skin by a doctor
2. Dermoscopy, which uses a dermoscope to examine the skin and evaluate skin conditions
- Dermoscopy can show features such as branched blood vessels with rounded ends, white criss-cross areas around blood vessels, yellow areas with no structure, and red globules resembling drops of milk
- Dermoscopy can also help distinguish between Poroma and the more dangerous skin cancer known as Porocarcinoma
3. Biopsy, which involves taking a small sample of the skin to examine under a microscope
- This is the most surefire way of diagnosing Poroma
- Doctors may also use additional tests with special stains to accurately identify the condition if it looks similar to other skin cancers or a benign Poroma under the microscope
4. Investigation of the status of nearby lymph nodes and looking for signs of metastases in cases with suspicion of Porocarcinoma
