Introduction: Malignant fibrous histiocytoma (MFH) is a tumor which has a mesenchymal origin, and an uncertain histogenesis. MFH with
giant cell accounts for 3–15% of all malignant fibrous histiocytomas. Objective: To explore the histopathology, the diagnosis and the
treatment of MFH with giant cell of larynx. Patient and Methods: We report a case of a glottic MFH at a 59-year-old male, who has been
smoking for 30 years, and was hospitalized in June 2008 at Emergency County Hospital of Craiova. Results: The largely-sized tumor was
originated in glottic area, upper a left vocal cord, with no paresis. The tumor determined respiratory failure and dysphonia. Patient
underwent surgical excision of the tumor after an emergency tracheotomy. The immunohistochemical techniques proved positive for
vimentin, smooth muscle actin, CD68, CD34, bcl2, EGFR, S100, Ki67, and negative for CD117, NFT, chromogranin, c-erbB2,
CK34betaE12, MNF116, and p53. Conclusions: Malignant fibrous histiocytomas (MFH) with giant cell of larynx are very rare mesenchymal
neoplasm (this case seems the first reported). The diagnosis of MFH of larynx was difficult and the immunohistochemistry could have been

Malignant fibrous histiocytoma (MFH) is a tumor
which has a mesenchymal origin and an uncertain
histogenesis and it is mainly found in the limbs, the
abdomen and the retroperitoneum [1, 2].
The term MFH is used to describe a histiocytic-like
tumor with fibrous tissue .
Histologically, there are five subtypes of MFH .
The histological diagnosis is based on the
proliferation of neoplasic cells (fusiform and polypoid)
that look like fibroblasts and histiocytes, with aberrant
atypias and mitosis. They are organized in bundles
with a variable pattern. It is difficult to establish a
correct differential diagnosis
histological techniques and, in order to be sure we
need confirmation from immunohistochemistry to
distinguish it from other tumors with mesenchymal
differentiation [5, 6].
We have studied a very rare case of malignant
fibrous histiocytoma of larynx, with giant cell variety.
? Patient, Methods and Results
We report a case of a glottic MFH with giant cell.
59-year-old male patient, who has been smoking for
30 years, was hospitalized in June 2008 at Emergency
County Hospital of Craiova. He had had hoarseness for
six months and progressive dyspnea for a month. While
undergoing indirect laryngoscopy we discovered a
globular, red-violaceous, pseudopolypoid lesion on
medium third of vocal cord on the left side, with
ulcerated epithelial cover, with no vocal cord paresis,
having a diameter of approximately 15 mm. There was
no palpable cervical lymphadenopathy. Biological tests,
neck echography and pulmonary radiography were
Initially, we had performed an emergency
tracheotomy due to severe respiratory failure. After the
tracheotomy, we performed a direct microlaryngoscopy
with excision of the tumor (Figure 1), and with closure
of tracheotomy in next step.
The tumor was fixed in 10% formalin solution and
wax embedded. The lesion was morphologically studied
with Hematoxylin–Eosin stain. The histopatho-logical
study showed a malign proliferation with spindle cell
proliferation with whorl pattern beneath the epithelium
(Figure 2) and many multinucleated giant cells
placed among fusiform cell fascicules (Figures 3–5).
We noticed the appearance of frequent atypical and
typical mitoses (Figure 6) and of small necrosis zones.

performed using vimentin, smooth muscle actin, CD68,
CD34, bcl2, EGFR, S100, Ki67, CD117, NFT,
chromogranin, c-erbB2, CK34betaE12, MNF116, p53
antibodies (DAKO) and Streptavidin–Biotin method
(LSAB Kit, DAKO).
Vimentin (VIM) was positive diffused immunohisto-
chemical stain in spindle tumoral cells (Figure 7).
The histiocytic marker CD68 was positive in large and
giant tumoral cells (Figure 8). S100 was variable
positive in spindle-shaped cells (Figure 9). Smooth
muscle actin (SMA) was positive in medium-sized
vessels within the tumor mass (Figure 10), and focally
positive in spindle cells (Figure 11). CD34 was positive
in numerous vessels and negative in tumor (Figure 12).
Bcl2 was rare positive in tumoral cells. EGFR was
positive in blood vessels and negative in tumor cells
(Figure 13). Ki67 was positive in about 30–40% of
tumor cells nuclei (Figure 14). The immunohisto-
chemical techniques proved negative for CD117, NFT,
chromogranin, c-erbB2, CK34betaE12, MNF116, and
p53. The patient refused our proposal to undergo a
partial laryngectomy. The evolution in the following
two months did not show any recurrences.

Kauffman SL and Stout AP introduced the term
MFH in 1961 in order to describe a histiocytic-like
tumor with predominant fibroblasts .
Approximately 3 to 10% of all MFHs are localized
in the head and neck and the most common localizations
are in the naso-sinusal cavities (30%), the cranio-facial
bones (15–25%) and in the larynx (10–15%) [4, 7, 8].
Less than 50 cases (laryngeal MFH) have been
published in medical literature [9, 10].
MFHS are histologically divided into five types:
pleomorphic, myxoid, inflammatory, giant cells and
Giant cell rich malignant fibrous histiocytoma
accounts for 3–15% of all malignant fibrous
histiocytomas . This case is the first report of
laryngeal giant cell malignant fibrous histiocytoma in
medical literature (MEDLINE, PubMed search).
Laryngeal MFH is more commonly found at men
patients rather than in women patients . It appears
mostly in middle-aged or older adults .
Frequently, the primary localization of laryngeal
MFH at men is the glottis, whereas at women it is the
subglottis [4, 7, 13].
Dysphonia is the most common primary symptom;
dysphagia and dyspnea can also be observed, depending
on the size and the localization of the lesion . In our
case, severe dyspnea with dysphonia, stridor and
tiredness are due to large size of tumor and they were
necessitated emergency tracheotomy.
A direct laryngoscopy and tumor biopsy or
excision were essential for establishing a correct
In laryngoscopy, the most common presentation is
that of epithelial nodules or polyps . The great
dimension is due to patient negligence.
The final diagnosis is based on showing that
the tumor cells are histiocytes and that this is derived
from the mononuclear phagocytic system – essential to
distinguish it from other fibroblast like tumors .
Pathologically, MFH is composed of a mixture of
spindle-shaped fibroblastic tumor cells and bizarre
mononuclear histiocytic tumor cells arranged in whorl
pattern beneath the epithelium, and some multinucleated
giant cells. A pathological diagnosis, especially in head
and neck tumors, is difficult .
The neoplasic cells were diffused positive for
vimentin and histiocytic marker CD68, and focally
positive in spindle cells for neuroectodermic marker
(S100) and smooth muscle actin (SMA). In other
authors’ work, S100 and SMA were negative .
In our case, MFH had myofibroblastic features with
immunoreactivity for SMA.
Differential diagnosis includes: pleomorphic rhabdo-
myosarcoma, fibrosarcoma, spinocellular carcinoma,
angiosarcoma, hemangiopericytoma, pleomorphic lipo-
sarcoma and lymphoma .
Surgery with block resection of tumor is the first
choice of treatment for the majority of authors and
surgical technique varies, depending on the size and
localization of the tumor [12, 16–20].
Radiotherapy and chemotherapy does not have any
further advantages in comparison with surgical
treatment . Radiotherapy is used at patients with high
risks, at recurrence of non-operated patients and in cases
of metastasis to distance .
MFH of the larynx determines local and distance
metastasis, especially to brain and lungs [4, 12, 16, 17,
The prognosis depends on tumor differentiation,
vascular invasion, size and on the existence or not of
metastasis . Approximately 60% of the patients may
survive more than 5 years, and 40% of the patients may
survive more than 10 years .
Malignant fibrous histiocytomas with giant cell of
larynx are very rare mesenchymal neoplasm (this case
seems the first reported). The diagnosis of MFH of
larynx was difficult and the immunohistochemistry
could have been helpful.
