・・・昔、激しく日に焼けていた、という方の肩や背中にシミともほくろとも区別のつかないような斑点状の色素沈着がよくみられますが、これは、メラニンの摘落（てきらく）というものです。

melanin pigmentation
摘落 is a typo of 滴落, I believe. Please see the website below. You can see abstract both in English and in Japanese

Pigmentary incontinence is a phenomenon observed in some inflammatory skin disorders. Clinically it may be seen as a slate-colored pigmentation. Histologically it is seen as an accumulation of melanin in the upper dermis. The possible mechanism for development of pigmentary incontinence is discussed based on a review of the literature and electron microscopic studies of fixed drug eruption.

Dermal hypermelanosis can be due to the production of melanin by ectopic dermal melanocytes (dermal melanocytosis), or to an abnormal transfer of melanin from epidermal cells to the dermis (pigmentary incontinence).

leakage in the dermis of epidermal melanin also exists, a form of dermal hypermelanosis called pigmentary incontinence.

Dermal melanosis occurs when inflammation disrupts the basal cell layer, releasing melanin pigment, which is subsequently trapped by papillary dermal macrophages; this effect is also known as pigmentary incontinence.

Histologically, pigmentary incontinence is caused by melanosome translocation from the epidermis to the dermis, usually following dermo-epidermal junction damage.

eakage in the dermis of epidermal melanin also exists, a form of dermal hypermelanosis called pigmentary incontinence.

The dead keratinocytes spill their melanin into adjacent dermis in a processcalled pigmentary incontinence, where it is phagocytized by macrophages (melanophages).

Increased dermal pigmentation probably results from a dischargement of the melanin granules into the dermis secondary to melanocyte alterations.

上記の原文末尾の表現は、タイトルのように「これはメラニンの滴落によるものです」と書き直す必要があるようでございます。
