Pathology of Breast Cancer
Published in Raymond Taillefer, Iraj Khalkhali, Alan D. Waxman, Hans J. Biersack, Radionuclide Imaging of the Breast, 2021
The diagnosis of mucinous carcinoma in FNAB and core biopsy is usually not difficult. The clinical information on the age of the patient can easily exclude the possibility of mucocele as a differential diagnosis [25]. However, in the presence of a mixed mucinous carcinoma, FNAB or core biopsy can potentially miss the infiltrating component. This is prognostically important, since mixed forms of mucinous carcinoma behave the same as an infiltrating duct cell carcinoma [107]. Therefore, it may be necessary to perform a surgical biopsy to assess the patient prognosis on evaluation of the entire lesion.
The gastrointestinal system

There are three pairs of major salivary glands – parotid, submandibular, and sublingual – and numerous intraoral minor salivary glands. The most common lesion of minor salivary glands is the mucocele. The lesion is most often seen on the lower lip and is frequently due to leakage of mucus from a damaged duct (mucus extravasation cyst – Figure 10.14). A cyst-like cavity forms and consists of the escaped mucus and macrophages surrounded by granulation tissue. A ranula is a larger variant that occurs in the floor of the mouth and usually involves the sublingual glands. Alternatively, a mucous retention cyst results from the accumulation of mucus within a blocked salivary duct.
Emergency management of the complications of infective sinusitis

In addition to these systemic disorders, there may be local sinus pathology, such as a mucocele, that predisposes to the development of a complication. A mucocele will cause expansion and thinning of bone over a period of time. When sited in the frontal sinus, it can cause dehiscence of the anterior and posterior bony walls of the sinus, and in the ethmoid sinus place the lamina papyracea is at risk. Mucoceles are prone to becoming infected and develop into a mucopyocele. Should the bony walls of a sinus be dehiscent, infection is more likely to spread (Figure 6.3).
Ectopic tonsil in the floor of the mouth: A case report
Published in Acta Oto-Laryngologica Case Reports, 2021
The reported case was initially diagnosed as mucocele/sialoadenitis. The ectopic tonsil as a clinical entity was not encountered during the initial work-up diagnosis as the differential diagnosis of lump under the tongue or floor of the mouth are retention cyst, sialolithiasis, mucocele or ranula. This case report adds to the previous published cases and to the fact that the ectopic tonsillar tissue can present as local infection or inflammation. In the reported case there were signs of inflammation or infection as the tissue became larger in size and pus-like secretion was aspirated from the lump. Moreover, the bacteriological findings on culture and sensitivity examination confirm the fact that ectopic tonsillar tissue may become inflamed or infected, thus requiring immediate management [4].
Gold laser removal of a large ductal cyst on the laryngeal surface of the epiglottis

A 55-year-old man was referred to the clinic after a difficult intubation during an implantable cardioverter-defibrillator placement surgery, where a mass was reportedly blocking the view to the glottis. The patient described a prior “clothesline injury” that occurred at age 9 with no associated stridor or difficulty breathing. Postinjury, he experienced a peculiar and muffled dysphonia with no signs of dyspnea or dysphagia. A computed tomography scan confirmed the presence of a large mucocele in the supraglottic region (Figure 1). Flexible laryngoscopy revealed a mass originating at the right laryngeal edge of the epiglottis extending to the right aryepiglottic fold (Figure 2a). Although the mass was larger than most ductal cysts, no imminent airway obstruction was present. Normal arytenoid and vocal cord mobility were noted despite acquiring only a partial view of the glottis due to the obstruction caused by the mass.
Beyond the commonest: right lower quadrant abdominal pain is not always appendicitis

The mucoceles occur due to abnormal excessive accumulation of mucin within the appendicular lumen, leading to excessive cystic distention of the appendix on top of different pathologies. We had been confronted with two cases (0.2%) of appendicular mucocele (Figure 4) and only one (0.1%) as low grade mucinous cystic tumor (Figure 5). Both lesions were clinically presented as right iliac fossa distension and dull aching pain, with minimal leukocytosis. Pathologically, the appendicular mucocele could be subdivided into different types; according to the underlying etiology. It could be due to simple inflammatory retention mucocele, which may occur due to appendicular lumen obstruction by a faecolith or mucosal hyperplasia. Also, it may be mucinous cystadenoma, which is the most common or less commonly mucinous cystadenocarcinoma. [16,17]
