ENGLISH VERSION
Splenosis is a condiꢀon in which spleen ꢀssue
Addiꢀonally, there were accessory spleens and images
in the subcutaneous ꢀssue between the fibers of the
leꢂ laꢀssimus dorsi muscle. The largest image had a
diameter of 23 mm, with signal uptake similar to that
observed in splenic ꢀssue (Fig. 1).
grows and develops in heterotopic locaꢀons. The term

was first used by Buchbinder and Lipkoff in 1939 . The
difference between splenosis and ectopic spleen is
that the laꢄer is a congenital condiꢀon that is more
prevalent, situated in close proximity to the splenic
hilum and has direct vascularizaꢀon from a splenic
artery branch.
We decided to perform a diagnosꢀc surgical
resecꢀon to determine the origin of the tumor, as we
suspected an intractable progression of the underlying
disease (Langerhans cell hisꢀocytosis), and the tumor
was increasing in size. The procedure was performed
under deep sedaꢀon and local anesthesia. A fibrous
nodular lesion measuring approximately 5 × 2 × 2.5
cm with a hard elasꢀc center was idenꢀfied within the
laꢀssimus dorsi muscle. The surgical specimen was
then divided into two, revealing a brownish nodular
area of approximately 20 mm in diameter with a
satellite nodule of approximately 0.6 mm in diameter.
Both nodules were in contact at one of their edges (Fig.
2). The paꢀent was admiꢄed for 24 hours and then

most common sites of splenosis are the small bowel

We report the case of a 63-year-old male
paꢀent who reported chronic, conꢀnuous, dull pain
below, low in intensity, below the leꢂ scapula that
began six months before. The pain was associated with
a tumor that had grown progressively over ꢀme. He
sought medical care at the Department of Hematology
where he was being followed-up due to hisꢀocytosis.

A rounded dysmorphic splenic structure was observed,
