dominantly of cells showing granulocytic differ-
entiation (granulocytic sarcoma) or predomi-
nantly of cells showing monocytic differentia-
tion (monocytic sarcoma).1It occurs in 2 to 14%
of cases of acute myeloid leukemia (AML).2The
tumors may occur as extramedullary masses
without evidence of leukemia in blood or mar-
row, so-called nonleukemic granulocytic sarco-
mas, or in association with AML. The tumors
originally were called chloromas because of the
green color imparted by the high concentration
of the enzyme myeloperoxidase present in
myelogenous leukemic cells. Biopsy specimens
are positive for chloracetate esterase, lysozyme,
myeloperoxidase, and cluster of differentiation
(CD) markers of myeloid cells.3The tumors are
usually localized; they often involve bone,
periosteum, soft tissues, lymph nodes, or skin.
Granulocytic sarcomas are solid extra -
medullary tumors that can be composed pre-
Common sites are the orbit and the paranasal
sinuses, but other sites reported include the
gastrointestinal tract, genitourinary tract,
breast, cervix, salivary glands, mediastinum,
pleura, peritoneum, and bile duct. Granulocytic
sarcomas may occur at diagnosis of AML or may
precede the diagnosis; they have also been seen
in association with myelodysplastic syndromes
or myeloproliferative disorders and usually pre-
dict transformation to acute leukaemia.2
Patients with granulocytic sarcoma have a poor
prognosis and the majority of patients without
bone marrow infiltration at presentation die of
leukemia within an average of 16.5 months
after diagnosis.4,5Granulocytic sarcoma of the
breast is an unusual site of presentation occur-

Hodgkin’s lymphoma at autopsy and in up to
50% of those with leukemia. However, with the
exception of Burkitt lymphoma, ovarian involve-

A clinical diagnosis of fibroadenoma breast

Fine needle aspiration from breast lump and

cede the development of acute nonlymphocytic
leukemia, or be the sole manifestation of
In granulocytic sarcoma of the breast the
patients mainly present with the breast
engorgement and a painless mass without
associated local symptoms.6
In granulocytic sarcoma ovary both diffuse
and nodular growth patterns are encountered,
but sclerosis can distort these patterns and
result in compartmentalization of the neoplas-
tic cells, as well as growth as nests and cords.
The single-file arrangement of lymphoma and
leukemic cells may simulate metastatic carci-
noma, particularly one of breast origin.
Granulocytic sarcoma on routine stains is
often composed of cells with more finely dis-
persed nuclear chromatin and may have more
abundant cytoplasm, which may be deeply
eosinophilic. Confirmatory immunostaining
may be crucial in making the diagnosis.9
In granulocytic sarcoma the growth pattern
may simulate invasive lobular carcinoma or
malignant lymphoma. The neoplastic cells
forming broad sheets or cords invade into and
around normal mammary parenchymal struc-
tures. Intra-epithelial extension of the
leukemic infiltrate simulates in situ carcino-
ma. The diagnosis of granulocytic sarcoma
may be suggested by cytoplasmic granules in
maturing myeloid cells or by the presence of
relatively numerous mature myeloid cells scat-
tered throughout the lesion. Special stains are
especially helpful to establish the diagnosis.
The tumor cells do not contain mucin and they
give a negative reaction for immunocytochem-
ical epithelial markers such as cytokeratin and
anti-endomysial antibodies. The diagnosis of
granulocytic sarcoma can be established by
fine needle aspiration biopsy if immature mye-
locytic cells are recognized in the cytologic
The differential diagnosis
includes non-Hodgkin lymphoma (predomi-
nantly mucosa-associated lymphoid tissue lym-
phoma and diffuse large B-cell lymphoma),
small round cell tumors, granulosa cell tumor,
undifferentiated carcinoma and in case of
breast, lobular carcinoma also.12A complete
panel of immunohistochemistry is helpful to
recognize this entity with an isolated presenta-
tion. Granulocytic sarcoma is immunoreactive
for myeloperoxidase, CD117 and CD68, CD43
is positive in most of the cases, and 75% are
reactive for CD45. Lysozyme and CD68 PGM1
expression are evidence for monocytic differ-
entiation.13,14Multiple sites involvement in sin-
gle patient was reported in literature.6,15-20In
the presented case multiple sites (both
ovaries, both breasts, and leg swelling) were
involved. Due to the rarity of isolated granulo-
cytic sarcoma and different treatments, the
clinical outcome and the prognosis in this
group of patients is poor.
