Proteus syndrome is an extremely rare, complex hamartomatous disorder with markedly variable clinical expression. We present a case of Proteus syndrome with multiple disfiguring soft tissue masses that were present since early childhood. The lesions involved predominantly the right side of the body and included scoliosis, macrodactyly, and limited hyperostosis in the right foot. There was no evidence of cranial or skin lesions. The patient underwent multiple resections of soft tissue masses, including an amputation of the right foot because of severe gait disturbance. All specimens exhibited lipomatous lesions that were probably hamartomatous rather than neoplastic. She carried a diagnosis of neurofibromatosis for more than a decade, but a re-evaluation of clinical features and pathological findings prompted the diagnosis of Proteus syndrome. We believe that a more informed evaluation of the pathology material may help to identify this rare entity.

A 15-y-old castrated male Maine Coon cat was evaluated for an ulcerated soft tissue mass on the right hindlimb that had been observed for 4 mo and had grown rapidly. A 3 × 3 cm soft, raised, amorphous, and ulcerated subcutaneous mass was observed on the lateral right metatarsus. In-house cytology via fine-needle aspiration was nondiagnostic. Incisional biopsy of the mass and further staging was declined, and amputation was elected. The amputated limb was submitted for histopathology, which revealed severe chronic nodular granulomatous dermatitis and multifocal granulomatous popliteal lymphadenitis with large numbers of intralesional fungal hyphae. Fungal PCR and sequencing on formalin-fixed, paraffin-embedded tissue identified Chalastospora gossypii. No adjunctive therapy was elected at the time. The patient has done well clinically 1 y post-operatively. C. gossypii is a rare microfungus found worldwide and is considered a minor pathogen of several plants. To our knowledge, infection by this fungus has not been reported previously in veterinary species. Features in our case are comparable to other mycotic infections. Nodular granulomatous mycotic dermatitis and cellulitis, although uncommon, should be a differential for soft tissue masses in veterinary species; C. gossypii is a novel isolate.

Soft tissue masses are amongst the commonest complaints encountered in orthopedic practice. Of these, masses found in the hand and the wrist are presented at higher frequency. They are often painful and may cause limitation of movement. This work describes the prevalence and the nature of soft tissue masses in the hand and wrist encountered in routine practice. This work was performed to assess the characteristics of soft tissue mass in the hand and the effectiveness of ultrasonography in the diagnosis of soft tissue masses and their differentiation from other lesions in the hand and wrist. Orthopedic surgical conditions that involve soft tissue in the hand and wrist may remain a diagnostic challenge when clinical diagnosis is uncertain and standard X-rays are non-diagnostic. High resolution ultrasound is widely available, non-invasive, without damage of radiation, imaging modality that can help the diagnosis. We reviewed retrospectively 25 patients with soft tissue masses. We compared the ultrasound findings with the histological findings in seven operated patients. A substantial majority of these lesions occurred in the right hand: 79% of the lesions were in the dorsal aspect of the hand, of which 37% were distal to the wrist joint, among them 42% at wrist either radial or ulnar; and 21% of the lesions were found in the volar aspect, among them 17% at wrist aspect, either radial or ulnar side. No predisposing factors could be found. The findings of this study reaffirm the utility of ultrasonography as primary diagnostic tool in routine orthopedic practice.

Shed Light

This chapter aims to shed light on the relationship between the development of laterality and the learning of mathematics in early childhood education using the ABN method. Thus, the authors present an experience developed with 24 children of 4 and 5 years old from several sessions of physical education where laterality and mathematics were worked on in the framework of a project developed in the classroom. The neuropsychological laterality test and a psychomotor table with values referred exclusively to manual and foot laterality, and indicators referred to the ABN method were used as evaluation instruments. The results obtained indicate that students with homogeneous right- or left-handed laterality obtain better results, as well as those with crossed laterality, since they have defined their manual and foot dominance. However, students with undefined laterality obtain worse results, even showing a lateral tendency towards the use of the right side of the body.

AbstractBallismus is defined as rapid, forceful, shaking or throwing involuntary movement of the extremities, mainly proximal parts. When it affects half of the body (upper and lower limbs on one side), it is called hemiballismus. If it affects one limb, it could be labeled as focal or one limb ballismus. Any lesion (vascular, trauma, tumor, deposition, and demyelination) in the subthalamic nucleus of the basal ganglia results in ballismus. A rare entity such as copper deposition in Wilson's disease can manifest as ballismus. We describe a boy with Wilson's disease with focal ballismus of the right arm.

Primary muscle hydatidosis is very rare. Rupture and spreading of the cyst contents by improper handling may later cause secondary cyst or allergic reactions. Pre-operative recognition of a hydatid cyst is therefore critical. It often presents as a soft-tissue mass, however, and pre-operative recognition of this rare entity is clearly difficult. Here, a case of primary hydatidosis affecting the gracilis muscle is presented, and the magnetic resonance imaging, clinical and pathological findings are described.

Background and Objectives: The submandibular lipomas are relatively rare entity. The reported age of the patients were from birth to 84 years old, and average being 55.7 years. These are mainly asymptomatic and mostly cause aesthetic concerns. Deep lipomas, especially in the head and neck, are not commonly reported. To our knowledge there’s not even a single publication regarding the lipoma in the submandibular region in our mid western region as well as in our country.Presentation of case: A 72 years old female presented with complaints of painless progressive neck swelling in the right submandibular region for about 2 years. Clinically, it was thought to be submandibular gland neoplasm/ lymphadenopathy. Ultrasonography (USG) and fine-needle aspiration cytology (FNAC) were done. It was negative for malignancy. She underwent excision of the mass under general anesthesia without postoperative complications. The histopathology confirmed it to be lipoma. Discussion: Lipoma is a common benign mesenchymal tumour that is found almost anywhere in the body. However, a large lipoma is relatively rare in the submandibular region. On clinical doubt, one can rely on USG / MRI (magnetic resonance imaging) and FNAC to rule out diagnostic dilemma. The treatment of choice is simply excision. Conclusion: It’s a rare entity and may be the first report of a lipoma in the submandibular region in an elderly people. One should rule out its possibility while going through the submandibular region diseases.Janaki Medical College Journal of Medical Sciences (2016) Vol. 4 (2): 46-49

ABSTRACT A 6 mo old 13.5 kg (29.7 lb) male intact American Staffordshire terrier was evaluated for a history of supernumerary pelvic limbs, with malodorous discharge from a supernumerary penis. Imaging (radiographs, abdominal ultrasound, and computed tomography with excretory urogram) showed a supernumerary pelvis with associated pelvic limbs, no osseous continuity with the primary spinal column, a colonic diverticulum extending to the supernumerary pelvis, an enlarged left kidney with a ureter connecting to a single bladder, right renal aplasia, a single descended testicle in the primary scrotum, an intra-abdominal cryptorchid testicle, and two unidentifiable soft tissue masses. At surgery, a single ileum was present with a primary and accessory cecum and colon and the accessory colon entering the supernumerary pelvis. The accessory cecum and colon, right kidney, two unknown soft tissue masses, and the single descended testicle were removed. The right kidney had a ureter that anastomosed with the accessory colon at its entry into the supernumerary pelvis. The supernumerary pelvis and hind limbs were not removed. Five months after surgery, the dog was reported to be doing well clinically. Caudal duplication is extremely rare in veterinary medicine. The appearance of supernumerary external structures may indicate internal connections as well.

AbstractSchwannomas and neurofibromas are rare benign tumors originating from the peripheral nerve sheath. Tumors in neurofibromatosis are mostly neurofibromas and often appear in the soft tissue of peripheral nerves. In this report, a patient presented with two large adjacent soft tissue tumors in the right wrist and distal forearm which originated from a common nerve. A schwannoma had formed beside a neurofibroma from the ulnar nerve and induced numbness and paresthesia in the little and ring fingers. Although the patient had café au lait spots on the skin, neurofibromatosis was not suspected due to lack of symptoms. The patient was referred to the current research clinic suffering from two soft tissue masses in the wrist and ulnar nerve dysfunction. In neurofibromatosis patients, two tumors of a different nature originating from a common nerve close together have rarely been described in the literature. The patient was treated by en bloc excision of the mass while protecting the nerve fascicles. The follow-up results indicated no neurological symptoms and complete restoration of ulnar nerve function.

Background: Leiomyosarcomas of soft tissue are malignant tumours that are not infrequently encountered in clinical medicine and histopathology. Such sarcomas of the eye are, however, a rare occurrence. Purpose: Herein, the histopathological features of a case of conjunctival leiomyosarcoma are described. A 38-year-old HIV-positive male, who was otherwise fit and healthy, presented with redness of his right eye and a mass of the conjunctiva. Clinically, he did not have any soft-tissue masses elsewhere in the body. Method: He underwent monoblock excision of the conjunctival mass which was confirmed histologically to be a leiomyosarcoma. Unfortunately, the patient had not returned for follow-up examination. Conclusion: The differential diagnosis of a conjunctival spindle cell neoplasm is broad. While a spindle cell carcinoma is the most likely tumour, other tumours must be borne in mind so as not to misdiagnose primary sarcomas in this unusual location.
