Angiolipoma is a type of lipoma, a benign soft tissue tumor. It is distinguished by the excessive degree of vascular proliferation and the presence of mature adipocytes. It occurs commonly on the trunk and extremities. Angiolipomas larger than 4 cm are classified as “giant,” and due to their size, histological evaluation is necessary to exclude malignancy. We report a case of a male patient who suffered from a giant noninfiltrating intramuscular angiolipoma which formed after venipuncture in the antecubital fossa. Clinical examination showed a palpable painless soft mass. Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a giant angiolipoma on the right forearm. Surgical removal of the mass was performed, and the biopsy was negative for malignancy. To the best of our knowledge, this is the first report in the literature of posttraumatic intramuscular angiolipoma. Physicians and orthopedic/general surgeons should be aware of the possibility of soft tissue masses in a posttrauma situation.

Introduction: Giant cell tumor of the tendon sheath is an uncommon benign soft tissue tumor of the tendon sheath and synovium usually affecting the middle aged population.  Only 3-10 % of Giant cell tumor of the tendon sheath occur on foot. Of them 5 - 10 % present with erosion of bone. We present a case of 30 years old male who had Giant cell tumor of the tendon sheath on the foot involving the Flexor Hallucis Longs  and Extensor Hallucis Longus and eroding both the phalanges of the right great toe.

Oral Soft Tissue

An ectopic tonsil is defined as tonsillar tissue that develops in areas outside of the four major tonsil groups: the palatine, lingual, pharyngeal, and tubal tonsils. The occurrence of tonsillar tissue in the oral cavity in ectopic locations, its prevalence, and its developmental mechanisms that belong to its formation remain unclear. In this report, we describe a rare case of bilateral symmetric ectopic oral tonsillar tissue located at the ventral surface of the tongue along with two solitary cases arising from the floor of the mouth. The role of immune system and its aberrant response leading to ectopic deposits desires further studies. As an ectopic tonsil may simulate a benign soft tissue tumor, this case series highlights the importance of this entity in our clinical differential diagnosis of oral soft tissue masses.

A Minor

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.

Infantile fibrosarcoma is a rare soft-tissue neoplasm, which may render a diagnostic challenge leading to misdiagnosis and consequently an inappropriate treatment of patients. This study reports a case of infantile fibrosarcoma that mimicked a hemangioma in an 11-month-old girl. As the lesion signal in the MRI was not consistent with the diagnosis of hemangiomas, we performed a core needle biopsy, which its result was consistent with the diagnosis of infantile fibrosarcoma. The lesion was initially treated with surgical resection. However, the lesion recurred one year after the surgery. The recurrence was managed with debulking surgery. The fifth finger was necrotized during the hospitalization after the relapse surgery. Finally, the necrotic finger was amputated. Also, adjuvant chemotherapy was used to prevent further relapses. The 1-year follow-up of the patient was recurrence-free. These findings highlight the importance of considering infantile fibrosarcoma when an infant presents with a lesion that clinically mimics a vascular lesion.

Gardner fibroma (GF) is a benign soft-tissue tumor that is associated with Gardner syndrome and can progress to, or co-occur with, desmoid fibromatosis (DF). Herein, we report a unique case of an 11-year-old boy who presented with a rapidly growing soft-tissue mass after biopsy of a stable fat-rich lesion present in the calf muscles since infancy, with Magnetic resonance imaging findings suggesting an intramuscular adipocytic tumor. The resection showed GF and DF. DF arising from a preexisting GF (the so-called “GF-DF sequence”) is a well-documented phenomenon. Although immunohistochemistry was negative for nuclear β-catenin expression, a CTTNB1 S45F mutation, which has been associated with aggressive behavior in DF, was identified in both components using a next-generation sequencing-based molecular assay. This is the first time a mutation in CTNNB1 has been identified in GF and the GF–DF sequence, thus expanding our knowledge of the molecular pathogenesis of the GF–DF sequence and highlighting the role of molecular testing in pediatric soft-tissue tumors. The histologic findings of an adipocyte-rich intramuscular GF also are unique, expanding the morphological spectrum of GF and adding GF to the differential diagnosis of intramuscular lesions with an adipocytic component.

Superficial Soft Tissue

AbstractThe vast majority of soft tissue masses are benign. Benign lesions such as superficial lipomas and ganglia are by far the most common soft tissue masses and can be readily identified and excluded on ultrasound (US). US is an ideal triaging tool for superficial soft tissue masses. Compared with magnetic resonance imaging (MRI), High-resolution US is inexpensive, readily available, well tolerated, and safe. It also allows the radiologist to interact with the patient as a clinician. In this review, we describe and illustrate the lesions with typical (diagnostic) US features. When the appearances of the lesion are not typical as expected for a benign lesion, lesions are deep or large, or malignancy is suspected clinically, MRI and biopsy are needed. The management of suspicious soft tissue tumors has to be carefully planned by a multidisciplinary team involving specialized surgeons and pathologists at a tumor center.
