Mucocele (also known as ranula or salivary gland mucous cyst) of the newborn is a lesion present on the intraoral cavity, with the potential to interfere with respiration and feeding. In the present report, a case of mucocele in a 4-month female patient has been described. As conventional surgery can be followed by several complications such as intraoperative bleeding, difficulties in wound healing, and maintenance of sterility during surgery, in the present case, the use of diode laser has been planned.

Introduction: Mucoceles are common benign pseudocystic lesions of the oral cavity; their main etiological factors are trauma and ductal obstruction. Two histological patterns are found: mucus retention phenomenon (MRP) and mucus extravasation phenomenon (MEP). Mucus extravasation phenomenon is the more common histological subtype and it mainly affects the lower lip. Read More

Salivary gland lesions are rare in pediatric patients. In addition, the types of salivary gland tumors are different in their distribution in specific sites in the major and minor salivary glands in children compared with adults. This article reviews benign neoplastic and nonneoplastic salivary gland disorders in pediatric patients to help clinicians to develop an orderly differential diagnosis that will lead to expedient treatment of pediatric patients with salivary gland lesions.

Ranula is a salivary gland cyst which typically present as localized superficial swelling over the floor of mouth. Complex or plunging ranulas develop when the mucus extravasation extends through or around the mylohyoid muscle, deeper into the neck, and present with neck lump along with or without swelling over floor of mouth. We report a case of large plunging ranula presenting as an isolated large neck mass in a 38-year-old female patient. Read More

Purpose Of Review: Ranula is extravasation mucocele arising from the sublingual gland, influencing the swallowing or eating; this review focuses on the most recent literature pertaining to pediatric ranulas and aims to comprehensively describe the methods of diagnosis and management approaches.

Recent Findings: Ranulas consist of intraoral ranula and plunging ranula, which are frequently misdiagnosed, so it is vital for the differential diagnosis of pediatric ranulas to depend on the clinical examination, imaging and fine-needle aspiration cytology. Pediatric patients should first be observed for 6 months before other treatments. Read More

The three most frequently diagnosed salivary gland diseases are salivary gland infections, sialolithiasis and mucoceles. Salivary gland infections are usually of bacterial or viral etiology and can be divided into acute and chronic types. Occasionally they can result from obstruction of the salivary duct, an autoimmmune disease or cancer therapy. Read More

Mucoceles of the submandibular gland are extremely rare pathologic occurrences that present an investigative and management dilemma owing to their clinical indistinguishability from plunging ranulas. Of the few that have been documented, these mucous extravasation cysts involved the submandibular gland alone. We describe perhaps the first case of an extensive submandibular gland mucocele occurring in conjunction with a mixed ranula from the ipsilateral sublingual gland, and discuss the various considerations in the management of such lesions.

It is well documented and generally accepted that enlargement of parotid salivary glands, as part of HIV-related salivary gland diseases (HIV-SGD), may be the initial symptoms/manifestations of the HIV infection. Oral mucoceles and ranulas are also frequently described as oral manifestations, in association with HIV infection. However, little is known about these latter lesions as being the initial symptoms indicative of an HIV infection. Read More

There are a number of occasions when ranula-like lesions of the oral floor can develop that do not originate from the sublingual gland, or that arise from the gland with no tendency towards recurrence. The author advises that the unconditional removal of the sublingual gland should not be the standard treatment for all ranulas, and present four case reports to illustrate these and describe how they should be treated. All the patients were treated successfully with conservative management and retained normal functioning sublingual glands. Read More

Salivary gland lesions are uncommon in children and may be related to the parotid, submandibular or sublingual glands. Inflammatory lesions are the most common cause of salivary gland abnormalities in children and can be due to acute viral, acute suppurative, or recurrent acute or chronic inflammation. Intraparotid lymphadenitis may also occur, as in cat-scratch disease or in other causes of cervical lymphadenitis. Read More
