Hi there,

I can understand your concern.

These black moles are known as lentigines or melanotic macules.

These are benign & caused by hyperpigmentation in the epidermal layer.

Rarely, these macules may be associated with a syndrome called LAMB syndrome. LAMB (lentigines, atrial myxomas, mucocutaneous myxomas, and blue nevi) syndrome is one of the myxoma syndromes.

The lentigines most commonly are seen on the lips, face, sclera, and vulva.

The lesions are brown and can be as large as 1 cm in diameter.

The mucocutaneous myxomas appear as papules or dermal nodules at various sites on the body, including the breasts, shoulders, oral mucosa, and tongue.

Cardiac myxomas are rare and usually occur in the form of atrial myxomas, which are clinically evident as intermittent embolic episodes and valvular obstructions.

An association with benign thyroid nodules is noted.

In your case, it does not sound like LAMB sydrome.

These are just simple lentigines.
