Solitary fibrous tumor (SFT) is rare mesenchymal tumor usually arising from pleura. SFT can be found at all anatomic site in our body but incidence of SFT is much lower in head and neck region especially at lower neck area. We found a case of SFT that presented as a lower neck mass in a 41-year old woman. Ultrasonography showed a 3×1cm sized hypoechoic mass in the intermuscular fat plane of left lower neck, and computed tomography showed a well circumscribed, low-density mass with contrast enhancement. Fine needle aspiration showed no malignant cells with abundant red blood cells, but it was not possible to completely rule out malignant tumors or nodules clinically. Surgery was performed to make a definitive diagnosis and histopathology showed tightly packed, round to fusiform cells with staghorn shaped vessels at microscopic examination. The tumor cell were positive for CD34 but negative for CD31 and S-100 protein.

Whether benign or malignant, laryngeal and neck masses may involve the upper airway and obstruct breathing. While surgically-resectable malignancies are generally extirpated with adequate margins of normal tissue, benign lesions are usually excised conservatively. However, even benign masses may behave malignantly, necessitating more aggressive surgical resection. We present one such case.   CASE REPORT   A 35-year-old man from Cotabato City consulted due to difficulty of breathing.  He had a six-year history of progressively enlarging anterior neck mass with intermittent dyspnea, foreign body sensation, progressive dysphagia and hoarseness over the last three months. Physical examination revealed a well-defined, 5 x 6 cm smooth, firm, non-tender anterior neck mass that moved with deglutition.  Rigid endoscopy showed a right supraglottic mass with bulging of the right glottic and subglottic area, with a less than 10% airway opening. (Figure 1A) Both arytenoids were visibly mobile, but glottic closure was impaired. (Figure 1B) Tracheostomy and suspension laryngoscopy with biopsy yielded inconclusive results (fibromuscular tissue) and fine needle aspiration cytology (FNAC) of the anterior neck mass only revealed blood and colloid. Contrast computed tomography of the neck showed a well-marginated, hypodense, thick-walled, heterogeneously enhancing mass in the right laryngeal fossa measuring 2.86 x 1.78 cm with a larger extension anteriorly measuring 4.66 x 2.52 cm.  Effacement of the epiglottis and aryepiglottic fold was noted.  The hyoid and thyroid cartilage were intact, and the thyroid gland was normal.  (Figure 2A, B)   Because of inconclusive histopathological and cytological results, an incision biopsy of the anterior neck mass was performed.  Histopathological evaluation revealed spindle cell mesenchymal proliferation, and immunohistochemical stains showed positive immunoreactivity for CD34, with a weakly positive S-100 and negative SMA, favoring a solitary fibrous tumor.

Fibrous Tumor

A solitary fibrous tumor (SFT) is a benign neoplasm, firstly described as a mesenchymal tumor of the pleura. Its incidence range in the head and neck region is about 5–27%, but only rarely does it affect paranasal sinuses. The differential diagnosis is challenging, owing to its erosive growth pattern and immuno-histochemical features. SFTs have an aggressive behavior and an important recurrence potential. Therefore, a radical surgical excision is the gold standard therapeutic procedure. A rare SFT originating from the right maxillary sinus is reported here. The 37-year-old patient presented to the outpatient clinic with a painful expansive lesion in the whole right maxillary region. The overlying skin was inflamed and the patient had no epistaxis episodes. The 1.5 dentary element tested negative for vitality; however, a puncture of the lesion led to a hematic spill and no purulent discharge. An endoscopic-guided biopsy was suggestive either of SFT or hemangioperictoma, excluding a malignant neoplasm. A multi-equipe surgical team was activated. The lesion was embolized in order to achieve a good hemostatic control and, after 48 h, the neoplasm was radically excised with a combined open and endoscopic approach. The patient was disease-free at 12-month radiological and clinical follow-up. Given the rarity of this lesion and the delicacy required in addressing head and neck neoplasms, we believe that the present case report might be of help in further understanding how to approach cranio-facial SFTs.

Abstract Neonatal tumours in the neck region are a rare finding. Teratomas typically comprise all three germ cell layers with tissues usually foreign to the anatomic site of origin. Head and neck teratomas account a smaller part of congenital teratomas. They can cause major airway obstruction due to the external compression that oropharyngeal or neck masses produce. In addition, there can be an intrinsic lesion in the larynx or trachea. We describe a premature, 30-gestational week-old newborn with large subcutaneous neck mass. Pre-delivery ultrasound showed heterogeneous tumor structure and displaced larynx. The intubation was successful. The newborn developed respiratory distress syndrome immediately after birth which rendered the surgical removal of the neck tumor impossible. An autopsy was done, and the histopathology revealed mature teratoma comprising muscle, brain, salivary and pulmonary tissues, as well as well-developed hyaline membranes in the alveoli. The combination of the respiratory distress syndrome and the neck tumor compression proved fatal. Prenatal diagnosis, therapeutic options and ex utero intrapartum treatment (EXIT) procedures are discussed for the diagnosis and management of this very rare tumor.

Abstract Background: Solitary fibrous tumor is an uncommon mesenchymal neoplasm that originates from fibroblasts and occurs predominantly in the visceral pleura. Pelvic cavity small sized malignant solitary fibrous tumor is very rare; it is easily misjudged by surgeons as a benign lesion and resected by laparoscopic surgery. When accompanied by dedifferentiation, malignant solitary fibrous tumor is difficult to diagnose by pathologists. Here, we describe a challenging case.Case presentation: A 47-year-old man was accidentally found to have a pelvic mass for three months, with pain and distension for seven days. The mass was adhered and compressed to the ureter and bladder. The right side of the pelvic cavity had a palpable and substantial mass, with no obvious associated pain. With an assumed diagnosis of a benign tumor, the patient underwent laparoscopic surgery to resect the tumor. Histologically, spindle cell areas and dedifferentiated areas were observed. Immunohistochemical analysis of dedifferentiated regions revealed cytokeratin showed multifocal expression. Vimentin and CD34 were abnormal negative. This case was diagnosed as a MSFT with dedifferentiation. The patient was well after the operation, but, unfortunately, he had a recurrence one year later.Conclusion: Pelvic cavity malignant solitary fibrous tumor is a rare tumor that is in frequently dedifferentiated and exhibiting cytokeratin expression. The diagnosis of this type of tumor can be confusing, and it should be distinguished from Synovial Sarcoma, Liposarcoma, and other malignant tumors. The expression of cytokeratin and the absence of vimentin and CD34 are pitfalls to diagnosis. In this case, there was still a high degree of malignancy despite the small size of the tumor. Clinical-image-pathological multidisciplinary analysis has a great effect on diagnosis and therapy of diseases. This case is a cautionary tale for surgeons and pathologists.

Fibrous Tumor

Abstract Solitary fibrous tumors (SFT) rarely occur in the neck region and can be easily mistaken for more common tumors if the index of suspicion is not high. They are characterized by remarkable histologic variability. However, immunopositivity for CD34 and Bcl2 with immunonegativity for other markers aid in establishing the diagnosis. Distinction from the other common benign entities is essential, as SFT are tumors of low grade aggressiveness and unpredictable biologic behavior. Complete resection is the key feature determining outcome.

CONTEXT: Cellular angiofibroma of the vulva is a rare tumor that was first described in 1997. It occurs in middle-aged women (average age: 47 years), has small size (< 3 cm) and well-circumscribed margins. CASE REPORT: We describe a case in a 51-year-old woman whose preoperative diagnosis was confounded with Bartholin's glandular cyst. The neoplasia was well delimited and made up of three characteristic components: fusiform cells forming small fascicles, numerous blood vessels and adipose tissue interspersed between the fusiform cells. The stroma cells were positive for vimentin and negative for CD34, protein S-100, actin and desmin. The differential diagnoses for this tumor include aggressive angiomyxoma, angiomyofibroblastoma, lipoma of fusiform cells, solitary fibrous tumor, perineurioma and leiomyoma.
