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.

Plexiform neurofibroma is a benign peripheral nerve-sheath tumor, rarely involving major nerves of the extremities. In the literature, there are no clear treatment strategies for plexiform neurofibroma of major peripheral nerves. Our experience encountered two patients with plexiform neurofibroma of the median nerve, presenting with a palmar mass and symptoms of carpal tunnel compression. Preoperatively, plexiform neurofibroma was diagnosed on MRI and clinical examination. Both patients also experienced significant neurological deterioration, with finger numbness and increased nerve/tumor size. Potential malignant transformation was also considered. For these reasons, resection of the involved area of the nerve and repair were indicated. In both patients, intraoperative pathological diagnosis was plexiform neurofibroma. The 45-year-old male patient refused further surgery after carpal tunnel release, which was performed under axillary block. One year postoperatively, nerve compression symptoms decreased moderately. In the other patient, a 7-year-old boy, a significantly enlarged area of the median nerve was resected, and neurorrhaphy was performed. One year postoperatively, median nerve motor-sensory functions recovered completely. Four years postoperatively, no enlargement of the residual tumor was observed.

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.

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.

Nodular fasciitis is a benign reactive lesion, often mistaken for a soft-tissue sarcoma in clinical practice. Involvement of the finger is rare, and a finger joint even rarer. We report on the clinical, radiological and histological features of intra-articular nodular fasciitis in a 52-year-old man, originating from the proximal interphalangeal joint of the right ring finger, with cortical erosion of adjacent bone. The discussion is focused on the tumor diagnosis and therapeutic approach, the differential diagnosis and the importance of immunohistochemical staining to establish the final diagnosis.

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.
