The psoas major muscle is one of the three muscle chiefs of the ilio-psoas muscle. The pathological processes concerning it are dominated by tumor lesions which are mostly malignant. The diagnostic approach is based on the clinic and the abdomino-pelvic scanner. If necessary, it will make it possible to direct a puncture and / or a biopsy. We report the observation of a 33-year-old patient admitted to the Bouaké University Hospital presenting with a mass in the left iliac fossa and an intermittent claudication of chronic evolution in whom the diagnosis of a psoas tumor was diagnosedthrough the abdomino-pelvic scanner and the pathology concluded to an angiomyolipoma.

Primitive myxoid mesenchymal tumor of infancy (PMMTI) is an extremely rare soft tissue tumor with only a few cases. Herein, we report a case of 5-months-old girl presenting with a soft tissue mass on the sole of the left foot that recurred 2months after a first resection. The Doppler ultrasound imaging showed abundant blood flow in the tumor. Magnetic resonance imaging (MRI) showed a well demarcated tumor on the sole of the left foot. The surgically resected tumor consisted of primitive mesenchymal tumor cells dispersed in a myxoid background with delicate small blood vessels. Immunohistochemically, tumor cells expressed vimentin but were negative for AE1/AE3, Desmin, Muscle-Specific Actin, MyoD1, Myogenin, CD34, S-100 protein and CD99. Fluorescence in situ hybridization (FISH) showed absence of chromosomal translocation involving SYT and ETV6. Thus, the patient was diagnosed with a primitive myxoid mesenchymal tumor of infancy. To our knowledge, this is the first case of PMMTI affecting the sole of the foot.

Benign and malign tumors can affect the temporomandibular joint (TMJ) as any other articulation. Nevertheless, TMJ tumors are rare and mostly benign. Their clinical expression is varied including symptomatology similar to TMJ dysfunctional disorders, otologic or neurologic pathologies. In some cases, they remain totally asymptomatic. Hence, diagnosis is difficult since the symptomatology can be misleading with TMJ dysfunctional disorders or otologic disorders wrongly diagnosed. There is thus frequently a long delay between symptoms onset and diagnosis. The great variety of TMJ lesions explains the wide range of possible treatment modalities, mostly based on surgery. We provide here a review of the lesions originating from the TMJ. Tumoral or cystic mandibular lesion affecting the TMJ through local extension will not be discussed. Osteoma, osteoid osteoma, osteoblastoma, chondroma, osteochondroma, chondroblastoma, tenosynovial giant cell tumors, giant cell lesions, non-ossifying fibroma, hemangioma, lipoma or Langerhans cell histiocytosis are all possible diagnosis among the benign tumors found in the TMJ. Pseudotumors include synovial chondromatosis and aneurysmal bone cyst. Finally, malign tumors of the TMJ include mainly sarcomas (osteosarcoma, chondrosarcoma, synovial sarcoma, Ewing sarcoma, and fibrosarcoma), but also multiple myeloma and secondary metastases. We will review the clinical, radiological and histological aspects of each of these lesions. The treatment and the recurrence risk will also be discussed.

OBJECTIVE: To provide a systematic review on ophthalmologic presentations of dermatofibrosarcoma protuberans (DFSP) in conjunction with a case report of primary orbital involvement by this tumor.
METHODS: A thorough electronic search on PubMed, Medline, Scopus, EMBASE and web of science databases was performed. All available data from reported cases along with our described case were extracted and analyzed.
RESULTS: We describe a 66-year-old male with primary orbital DFSP who was managed by total excision of the tumor without recurrence after 18 months of follow-up. In the literature, 14 studies reporting 15 cases were identified and reviewed. Our review topics included epidemiology, clinical presentations, pathologic features, differential diagnosis, imaging, treatment and prognosis.
CONCLUSIONS: Rarely, but crucially, ophthalmologists may encounter DFSP in the orbital or periorbital area. They should be familiar with the pathologic nature and treatment options for this tumor. This diagnosis should be kept in mind when approaching a case with a non-tender, nodular, firm, mass or more rarely an indenting orbital mass.

Among soft tissue tumors, nodular fasciitis is a relatively common tumor process, which occurs in the 30 first years of life. Nodular fasciitis is a benign tumor with a rapid proliferation of myofibroblastic cells, which develops at the expense of a muscular fascia in the subcutaneous tissue. Usual localizations are the trunk and upper limbs. Difficulty of diagnosis consists in the need to eliminate many differential diagnoses especially malignant tumor processes. From a clinical point of view, the rapid development of nodular fasciitis (from some days to some weeks) must fear a malignant process. This benign lesion, which does not recur (even if incomplete resection), may regress spontaneously. We report such a tumor located at the cubital fossa confirmed by a pathological examination.

Elastofibroma dorsi is a benign tumor which usually occurs at the inferior angle of the scapula. We retrospectively reviewed 14 cases of elastofibroma dorsi, in nine patients. The patients were hospitalized in the departments of plastic surgery, orthopedic surgery or visceral surgery. Mean age was 67 years. The location of the lesions (bilateral in five patients) was typical, in the thoracoscapular region. Nine lesions were removed surgically, six shoulders were asymptomatic after surgery. Elastofibroma is a rare, slow-growing lesion. It occurs in connective tissue of the infrascapular region of elderly patients. The pathogenesis of the lesion still remains unclear. MRI and computed tomography are useful for assessment of elastofibroma dorsi, and can potentially help avoid the need for unnecessary biopsy and surgery, especially in the asymptomatic patient. It should be surgically removed only in symptomatic patients.
