Adolescent Woman

A 16-year-old woman presented with a painless, progressive, hard swelling in the left inferolateral orbital wall for the past 1 year. There was no diminution of vision or limitation of ocular motility. Imaging revealed an intraosseous, well-defined, expansile, soft tissue lesion in the inferolateral wall of the left orbit. A left anterior orbitotomy with complete surgical excision was performed. Histopathological evaluation of the specimen revealed fascicular pattern of spindle cells with a rich network of slit-like, branching blood vessels. Tumour cells exhibited smooth muscle actin and vimentin positivity but were negative for CD-34 and STAT-6. In absence of any systemic manifestation, a diagnosis of intraosseous solitary orbital myofibroma was made. The case highlights the importance of integrating clinical, radiological and histopathological features in overcoming the diagnostic challenge of differentiating myofibroma from other mesenchymal neoplasms. It also brings forth the importance of complete resection and curettage to prevent recurrence.

Abstract Myofibromas are benign mesenchymal neoplasms of myofibroblastic origin. Most present as solitary lesions at any age, but the presentation of multiple lesions in newborns and infants is known as infantile myofibromatosis. Multicentric lesions commonly involve soft tissues and bone and may involve internal organs, where they are associated with an unfavorable prognosis. Solitary lesions involving the viscera are rare. We report a case of a 3-month-old male infant with a left testicular mass detected during an evaluation for suspected torsion. The patient underwent orchiectomy, revealing a nodular mass with grossly evident foci of necrosis. Histologically, the lesion exhibited small fascicles of plump eosinophilic, smooth muscle actin–positive spindle cells, alternating with larger areas of primitive cells with vesicular nuclei and scant cytoplasm arranged around a hemangiopericytoma-like vasculature. To our knowledge, this is the first report of a myofibroma localized within the testis.

In each of seven ferrets ( Mustela putorius furo) with leiomyosarcoma, a single dermal mass was identified and biopsied. Each mass consisted of a well-demarcated but nonencapsulated proliferation of large spindle- to strap-shaped cells arranged in interwoven bundles. The cells resembled the smooth muscle cells of the adjacent arrector pili muscles, but with marked nuclear pleomorphism. Immunohistochemical staining for smooth muscle actin, desmin, and vimentin was positive and staining for myoglobin and cytokeratin was negative. Follow-up on three of the ferrets indicates that the prognosis is good following complete surgical excision.

Cells Of Cajal

Gastrointestinal stromal tumors (GISTs) are potentially aggressive mesenchymal neoplasms with spindle cell, epithelioid, or mixed morphology. They typically express CD117, DOG1, and CD34 and can be diffusely and strongly positive for h-caldesmon. Leiomyomas are benign smooth muscle neoplasms that can arise in a variety of visceral and soft tissue sites, including the gastrointestinal tract. We illustrate a case of a neoplasm of the gastroesophageal junction that was clinically suspected to be a GIST. Histology showed a tumor composed of ovoid and spindle cells arranged in short intersecting fascicles, which was positive for desmin, smooth muscle actin, and h-caldesmon, with a prominent interspersed subpopulation of CD117- and DOG1-positive elongated or dendritic-like cells. These features were of leiomyoma with entrapped interstitial cells of Cajal (ICC). The recognition of possible entrapment of ICC in leiomyomas as a potential mimic of GIST is important for correct treatment and prognostication.

Giant Lipoma

Lipoma is the most common benign tumor of adipose tissue. Giant lipoma of breast is very rare.Majority of them are small in size, slow growing and asymptomatic until they reach large size. Most patients seek medical advice due to asymmetry in the breast and due to fear of malignancy. Breast lipomas pose a diagnostic challenge due to similarity of their texture to normal breast parenchyma and make it difficult to distinguish from other common breast lesions. The clinical and radiographic identification of breast lipoma remains challenging. Complete surgical excision with the capsule is essential to prevent recurrence. Breast reconstruction may require, to prevent asymmetry following surgical excision of giant breast lipoma. High degree of clinical suspicion and histolopathological correlation will help in preopertaive diagnosis of this clinical condition. Here, we report a case 50- year -old woman with left breast lump which clinically, radiologically and on fine needle aspiration cytology was diagnosed as phyllodes tumor, but after surgical excision it was reported as breast lipoma on final histopathology.

Primary Leiomyosarcoma

Abstract Primary leiomyosarcoma of the pancreas is a rare tumor for which only 21 reports appear in the world literature. We describe an additional case of pancreatic leiomyosarcoma in a 76-year-old man, who complained of persistent high fever. Histologic examination revealed a pleomorphic spindle cell tumor. Reactivity for muscle-specific actin, α-smooth muscle actin, and basement membrane components, along with negative staining for epithelial and neural markers, were consistent with a smooth muscle sarcoma. The patient died of disease 1 year after complete surgical excision. This report highlights the need to use a complete antibody panel in order to accurately immunophenotype pleomorphic malignant tumors of the pancreas. A review of the cases compiled in the literature indicates that pancreatic leiomyosarcoma, like its counterpart arising in deep soft tissues, is an aggressive neoplasm characterized by short survival and a high rate of metastases.

This report describes a rare case of nodular fasciitis (NF) of the oral cavity, discussing the clinical, histological, and immunohistochemical characteristics. Histopathologic diagnosis of this type of lesion can be challenging due to its differential diagnosis, which principally includes sarcoma. The patient presented with a painless, well-defined nodule, reported as increasing in size, located at the apical aspect of the upper left buccal sulcus. Histologically, the lesion revealed spindle cell proliferation arranged in fascicles, while immunohistochemistry demonstrated positivity for smooth muscle actin. Eight months after complete surgical excision, no signs of local recurrence have been observed.

Solitary fibrous tumors are uncommon mesenchymal neoplasms that were initially described as pleural tumors, but in recent years, numerous extrapleural sites have been reported. A solitary fibrous tumor is characterized as a circumscribed, painless mass with a patternless growth pattern, positive CD34 spindle-shaped cells, bcl-2, and dense keloidal collagen with areas of hypercellularity and hypocellularity. This case report describes a 55-year-old male veteran who presented with a rare manifestation of an extrapleural solitary fibrous tumor of the medial right hallux. Microscopic and immunohistochemical findings were consistent with the previously documented characteristics of solitary fibrous tumors. Complete surgical excision of the tumor is the treatment of choice.

Primary retroperitoneal tumours pose a diagnostic dilemma and therapeutic challenges because of their location and late detection. Localized Castleman Disease (CD) in retroperitoneal location is a rare occurrence, with incidence of only 4% cases occurring in diverse locations like retroperitoneum. A rare case of unicentric localized Castleman Disease localized in broad ligament is hereby reported which was clinically & radiologically suspected as broad ligament leiomyoma but finally diagnosed as Castleman’s Disease, hyaline vascular type in a young female posing a diagnostic challenge both for the pathologist and clinician. Definite diagnosis is essential as complete surgical excision in case of unicentric Castleman’s Disease has good prognosis after resection.

Objective One of the principal objectives in treatment of facial nevus is to minimize psychological damage and encourage the child's schooling by the best possible cosmetic result. There are several therapeutic techniques: grafts, flaps, dermal regenerator, and tissue expanders. Materials and Methods We reviewed 10 patients with facial nevus higher than 10 cm treated in the past 8 years. Our treatment protocol includes serial expander implant to remove everything that does not involve the eyelid and nasal pyramid. Ten patients were included, between 8 and 36 months of age. A median of 4 (2–6) surgeries were conducted, and the number of implanted expanders was 1 to 3 in each session. There were only minor complications in two patients, infection that responded to antibiotic therapy and minimal dehiscence of incision forcing resuturing. The median follow-up was 1.6 (1.3–3.4) years. Conclusion Tissue expansion has become in recent years the treatment of choice for facial nevus in children, obtaining the best aesthetic result because the defect is covered with similar characteristics in color, texture, and relief skin. It is essential that the reconstruction is done by specialized units and we recommend complete surgical excision before starting school.

Conjunctival Myxoma

Conjunctival myxoma is an exceptionally rare, slow-growing, benign neoplasm of primitive mesenchyme origin. Forty-one cases of conjunctival myxoma from a literature review, including the authors' case, are listed. The usual clinical history is a painless mass appearing during months to years. Grossly, the tumor is a well-circumscribed, cystlike, gelatinous, yellow-to-pink, translucent-to-solid mass. Microscopically, the hypocellular tumor contains stellate- and spindle-shaped cells in a mucoid stroma with abundant hyaluronic acid mucopolysaccharides. Vimentin and α-smooth muscle actin highlight the spindle and stellate cells. S100 protein and desmin are negative for the tumor cells. Treatment is complete surgical excision, with no recurrence reported in the follow-up period. Notably, conjunctival myxoma may be associated with Carney complex, an autosomal-dominant disorder associated with skin pigmentation, endocrine abnormalities, and myxoma of the heart and eye. Physicians should appreciate this unique ocular tumor because of its potential association with Carney complex.
