Galactocele is a rare breast condition in infants. Here, we report a 16-month-old boy who developed progressive left breast enlargement. Ultrasonography and magnetic resonance imaging revealed a 4 cm cystic lesion at left breast. Hormonal assay showed transient hyperprolactinaemia with no known cause identified. Subsequently, galactocele was confirmed on histopathological examination after complete surgical excision. No recurrence was observed on regular follow-up.

Papillary Endothelial Hyperplasia

Abstract BACKGROUND AND IMPORTANCE: Papillary endothelial hyperplasia (PEH) is a rare form of exuberant reactive endothelial proliferation that can mimic neoplasm. We report the largest series of patients with histologically confirmed intracranial extravascular PEH developing in the field of previous treatment with stereotactic radiosurgery. CLINICAL PRESENTATION: We collected the clinical, radiological, surgical, and pathological findings from 4 patients in whom intracranial extravascular PEH developed after treatment with stereotactic radiosurgery. In all patients, the development of an enlarging hemorrhagic mass lesion at the site of previous radiotherapy on magnetic resonance imaging was radiographically suspicious for neoplasm and prompted biopsy or resection. All 4 patients elected to undergo biopsy or surgical resection. Histological examination of the biopsy and resection specimens in all patients demonstrated the classic features of PEH. CONCLUSION: The interval to the development of PEH ranged from 5 months to 6 years, 10 months. Clinical follow-up was available for 3 of the 4 patients. None of these 3 patients have demonstrated evidence of recurrence during a mean follow-up period of 22 months (range, 15–30 months). These patients share common radiological features, potentially allowing preoperative diagnosis and improved guidance of clinical management. These cases suggest a link between radiosurgery and the development of PEH. These findings also suggest that PEH should be considered in the differential diagnosis for patients treated with radiosurgery in whom a hemorrhagic mass lesion subsequently develops at or near the site of previous treatment. We think that complete surgical excision is the best treatment for intracranial PEH.

Introduction. Myoepithelioma primarily affects the parotid gland and usually presents as a slow-growing painless lump. The aim of this paper is to report a case of myoepithelioma in the mouth floor. Case outline. A young man noticed a painless increased volume in the left side of the mouth floor region, which after one year of evolution presented as a sessile tumor with normal colored mucosa and the absence of secretion output. Computed tomography with contrast showed an image with slightly heterogeneous density, with well-defined limits. Incisional biopsy was performed under local anesthesia, and pathology examination of the sample revealed a myoepithelial neoplasm. Total excision of the lesion was performed under general anesthesia, and histopathological examination confirmed the diagnosis of the salivary gland myoepithelioma. The patient did not present signs of relapse after a year of follow up. Conclusion. Despite the fact that myoepithelioma originating in the salivary gland are considered rare, especially in the mouth floor, this tumor should be considered in the differential diagnosis of similar lesions. Proper treatment appears to be complete surgical excision and post-operative follow-ups shows should be carried out as long as possible, despite the fact that relapses are extremely rare.

Retroperitoneal Schwannoma

Background and Objectives: Retroperitoneal schwannoma is a very rare case of schwannoma which commonly occurs in the other part of the body. However, it is difficult to distinguish schwannoma from other tumors before pathological examination because they do not show specific characteristics on imaging study such as ultrasound, computed tomography (CT), and magnetic resonance image (MRI). Case summary: A 60-year-old male showed a retroperitoneal cystic tumor which is found incidentally during evaluation of coexisted bladder tumor. Neurogenic tumor was suspicious for the retroperitoneal tumor through pre-operative imaging study. Finally, a schwannoma was diagnosed by immunohistochemical examination after complete surgical excision laparoscopically. Conclusion: As imaging technology is developed, there may be more chances to differentiate schwannoma from other neoplasm. However, still surgical resection and histopathological examination is feasible for diagnosis of schwannoma.

AbstractThe present study is a case report of vulvar lipoma. The vulva is a rare site for the development of lipomas, and the aim of the study is to determine if the current imaging modalities can diagnose lipomas correctly. A 43-year-old patient presented with a painless, slowly progressive, oval, mobile and non-tender right vulvar mass compressing the vagina and totally covering the introitus. Both the ultrasonography and magnetic resonance imaging (MRI) exams suggested the diagnosis of lipoma. Surgical excision was performed, and the histopathological examination of the mass confirmed a lipoma.

Cardiac Myxomas

Cardiac myxomas are the most common primary cardiac tumors and are typically attached to the interatrial septum. Left ventricular myxomas are exceedingly rare and presentation in children is all the more uncommon. We report a case of left ventricular myxoma with very atypical cystic appearance raising an initial suspicion of a hydatid cyst. Subsequently, cardiac magnetic resonance imaging was done, which ruled out the diagnosis of hydatid cyst. Complete surgical excision was done through transaortic and transmitral route. Histopathological examination revealed it to be a cardiac myxoma with vascular proliferation, which on echocardiography had appeared as a polycystic lesion. This is a very unusual histopathological presentation of cardiac myxoma.

Glial Heterotopia

Nasopharyngeal glial heterotopias is an extremely rare, nonhereditary, developmental malformation manifesting as a mass composed of mature neural tissue with no intracranial continuity. Glial heterotopia is a rare, non-neoplastic, extracranial midline malformation. Nasal glioma is the most frequently encountered entity among congenital nasal masses. Cases which are associated with intracranial extension are termed as encephalocele. It must be considered in the differential diagnosis of airway obstruction in neonates. Magnetic resonance imaging is mandatory to rule out intracranial extension. We report a rare case of heterotopic brain tissue in nasopharynx with no intracranial extension to attract attention to the diagnostic workup of nasopharyngeal obstruction in a neonate with respiratory distress. Clinical examination and radiological studies are diagnostic while early surgical excision and histopathological confirmation is the gold standard. This baby underwent complete intranasal endoscopic excision of mass on day 20 of life. The postoperative course was uneventful and the baby is growing well on follow-up. This case would be one of the few cases reported from India.

Mucinous cystadenocarcinoma of minor salivary glands is an extremely rare entity that has only recently been described, with a few published cases in the English literature. A 42-year-old woman with a history of a surgically excised mucinous cystadenoma of the oral tongue, presented with a painful swelling in the oral tongue slowly growing for 1 month. On clinical examination, there was a firm, relatively well-circumscribed mass in the left posterior border of the mobile tongue. Subsequent MRI scan revealed a heterogeneous lesion composed of multiple cysts separated by contrast enhancing septa, in the posterior two-thirds of the left tongue. Imaging findings were similar to those of the previously resected mass, suggesting local relapse of the primary lesion. A complete surgical excision was performed and the histopathological examination revealed typical features of a low-grade mucinous cystadenocarcinoma of minor salivary glands.

Dermoid cysts are rare benign tumors that arise from ectopic epiblastic inclusions and account for 0.4% to 1.5% of all tumors. They are usually 1 to 5 cm in size and composed of a pasty semisolid material. The orbital dermoid cyst is the most common type. Dermoid cysts can also occur in the spinal cord, ovaries, and pancreas. We encountered a 24-year-old man with a dermoid cyst over the left sternoclavicular joint. He reported intermittent secretion of a white tofu-like exudate from an underlying congenital sinus tract since birth. The secretion had turned hemorrhagic for the last month and had been accompanied by progressive swelling and pruritus for 1 week. Ultrasonography and magnetic resonance imaging revealed characteristics of a dermoid cyst, and histopathological examination confirmed the diagnosis. The patient underwent surgical excision of the cyst under local anesthesia. The incision healed well with no postoperative complications. Considering that a dermoid cyst has the potential to become infected or progress into squamous cell carcinoma, its removal at an early stage is suggested. Few reports in the literature have described a dermoid cyst that secretes hemorrhagic contents from a congenital sinus tract. We present this case to provide a reference for clinicians.

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.

Attention To Detail

Ductography or galactography is a technique used in the diagnostic workup of unilateral, single duct, spontaneous, and bloody or clear nipple discharge. Mammographic imaging with magnification may reveal the source of the discharge. The technique is challenging, yet it can be mastered with attention to detail, a well thought-out protocol, and practice. Imaging findings can be non-specific, yet may guide biopsy or surgical excision. Now with the wide use of breast magnetic resonance imaging (MRI), which has been shown to be more sensitive for lesion detection, ductography is used less frequently. This chapter, appearing in the section on interventions and surgical changes, reviews the indications, procedure protocols, and pitfalls, as well as the management and imaging follow-up for ductography or galactography.
