Why do I have a black pimple like spot on my penis?

Hello,

Welcome to icliniq.com.

Kindly send a more clear picture delineating the suspected "pimple" lesion (attachments removed to protect the patient's identity). Please answer the questions below for a better understanding of the condition.

1) Did you observe any change in the growth of the lesion?

2) Did you notice any pus formation on the pimple-like lesion?

3) Did you notice redness, swelling, or itching around the lesion?

4) Did you have any systemic symptoms like fever or other symptoms that may help correlate with systemic disease?

5) Did you have any unprotected sexual exposure?

6) Did you have any history of chickenpox or herpes in childhood?

The probable cause behind this could be herpes or any benign lesion, and the lesion looks probably like a penile nevus with herpes.

Do not engage in sexual intercourse before getting the results.

Get the following investigations done:

1) STD panel tests- Herpes, Chlamydia, Gonorrhea, Treponema pallidum, Hepatitis B & C, HCV, HIV.

2) General - CBC (complete blood count), ESR (erythrocyte sedimentation rate).

Hello,

Welcome back to icliniq.com.

In my opinion, these are the following possibilities in differential diagnosis:

1) Pimples and blackheads- Most pimples and blackheads are harmless and often resolve in a few months with basic at-home care, such as good hygiene and warm compresses. A mild infection or blocked pores may have caused it, often observed as dark spots on the scrotum.

2) Hyperpigmentation- It occurs when some areas of the skin develop more pigment. This can appear as a variety of rare skin lesions, such as freckles, moles, sunspots, and stretch marks, and are harmless.

3) Angiokeratoma- This condition causes small blood vessels to widen, resulting in non-cancerous skin lesions that may be dark red or blue.

Please share all your patient records with any skin specialist or dermatologist.
