Case of Lactation in a Male. By C. W. Hornor, M. D., of
Philadelphia. (Communicated by Professor Dunglison.)
Dear Sir,—According to your request, I send the particulars of
the case of lactation in an adult male. It occurred in the person
of an athletic American, named Charles Collins, aged 22 years, a
blacksmith, working at his trade in New York. About the 10th
of February last, his attention was first drawn to his left breast,
which appeared to be enlarging, and continued to increase in size
for three weeks, when he came to Philadelphia. After being in
this city for three weeks, he became quite anxious in regard to his
condition, for although he suffered very little pain, the mamma had
become quite as large as that of a female nursing. He therefore,
through the persuasion of an aunt, was, on the twenty-third of
March, induced to apply at the Clinic of the Jefferson Medical
College to consult the faculty of that Institution. His case came
up before Prof. Mutter, who, upon examination, found the mammary
gland largely developed, and filled with the lacteal secretion,
which differed in no wise from that of a mother. He could assign
no cause for this freak of nature ; his health was very'good, and
the other breast natural. A soap plaster was prescribed, and
compression ordered to be kept up, which he persisted in for full
six weeks, when the gland returned to its usual size ; and when I
saw him this morning at Fairmount, where he now resides, it was
in every respect like the other.
