Most congenital masses of the mouth floor are cystic, irrespective of their origin. They may obstruct airway or digestive tract or may present other complications. Recognizing and treating these masses expeditiously is imperative. Choristoma is a mass of normal tissue in an abnormal location; they are classified according to the predominant epithelial lining. Few cases have been reported lined with gastric and respiratory epithelia within the same cyst. This case report presents a 5-month-old boy with an infected choristoma involving the floor of the mouth and its successful management...

REVIEW
Hershel R Patel, Curtis E Margo
Epithelial downgrowth is an uncommon complication of ocular surgery or adverse consequence of accidental trauma, caused by surface squamous epithelium that has gained access to the inner compartments of the eye. Once embedded in the eye, squamous epithelium spreads over contiguous structures, interfering with normal aqueous outflow and vision. The pursuit of improved therapies is ongoing, but the greatest chance of preventing blindness is with early recognition. Two cases of epithelial downgrowth diagnosed from a corneal button and an iris biopsy are presented to familiarize pathologists with this disorder...

Neuromuscular choristoma (NMC), also called neuromuscular hamartoma or nerve rhabdomyoma, is a rare lesion of the spinal and cranial nerves composed of skeletal muscle intimately associated with nerve fibers. Its origin has not been precisely clarified and a malformative event, resulting from aberrant differentiation or a true neoplastic growth, have been proposed by authors. We hereby present a cerebellopontine angle NMC enlarging the eighth cranial nerve in a 3-year-old child, that histologically appeared composed of a large amount of striated muscle mixed with nerve fibers...

A 25-year-old man with Type 1 diabetes mellitus experienced rapid visual decline and was scheduled for right cataract surgery. At the time of administering an inferotemporal retrobulbar block, a white discharge appeared spontaneously on the surface of the globe. Superotemporally a cyst was found and its contents were subtotally evacuated. Microscopically, eosinophilic, acellular material with chatter artifact and small vacuoles was detected and initially thought to represent a lens choristoma. This material stained moderately with the periodic acid Schiff method and was focally Congo red positive without apple green birefringence; it also stained blue with the Masson trichrome method...

Neuromuscular choristoma (NMC) is a rare benign peripheral nerve lesion consisting of mature skeletal muscle fibers admixed with nerve fascicles. Aggressive fibromatosis frequently develops in association with NMC, often after surgery or biopsy, but the exact pathogenesis is not known. We present a case of NMC complicated by aggressive fibromatosis evaluated by F-FDG PET/CT and examine the relationship of metabolic activity and MRI signal characteristics.

Neuroglialchoristoma is a rare cerebral heterotopia typically involving extracranial midline structures of the head and neck, including the nose, nasopharynx and oral cavity. It rarely involves non-midline structures, such as the middle ear, mastoid and orbit. We report the case of a 63-year-old woman with right-sided hearing loss and aural fullness who was diagnosed with neuroglialchoristoma of the middle ear and mastoid. To our knowledge, this is the first report on neuroglialchoristomawith massive tympanosclerosis...

Linear nevus sebaceous syndrome (LNSS) is characterized by nevus sebaceous, mental retardation, seizures, and ocular abnormalities such as complex limbal choistoma. A young male with history of mass in right eye and blackish discoloration of skin over right and left side of forehead since birth presented with foreign body sensation and diminished vision in right eye. Ocular examination showed mass over epibulbar region with chorioretinal coloboma and posterior staphyloma in right eye and megalocornea in left eye...

Ectopic cilia (EC) are a very rare condition with only few cases reported in literature. Many associations were seen with ectopic cilia which include distichiasis, choristoma and aberrant lacrimal gland, hypochromic nevus, atopic eczema and others. We are reporting a case of an 11-year-old girl with isolated left upper lid ectopic cilia, which was confirmed by surgical removal and histopathological study.

A six-year-old castrated male Maltese dog presented to a private animal clinic with a mass on the dog's lower lip without any other clinical signs. The mass (3 × 2 × 2 cm) was whitish and grossly well circumscribed, and a histopathological examination revealed that the mass was composed of normal cartilage tissue surrounded by fibrous connective tissues. Based on the gross findings, histopathology and anatomical location of the mass, the first diagnosis of a cartilaginous choristoma in a dog was made.

BACKGROUND: Mixed tumors of adenomatous and neuronal cells in the sellar region are an uncommon finding. The origins of these heterogeneous tumors are unknown, and management remains unsettled. We report a very rare case of anterior gray matter pituicytic heterotopia with monomorphic anterior pituitary cells that likely represents a variant of nonsecreting pituitary adenoma neuronal choristoma (PANCH) with no ganglion cells. We also review the current literature for the various clinical presentations of PANCH...

PURPOSE: To report a rare case of encephalocraniocutaneous lipomatosis (ECCL) presented with characteristic multiple organ involvement. METHODS: A 7-day-old white Iranian girl was referred with ocular, skin and brain abnormalities. RESULTS: The findings of nevus psiloliparus, eyelid choristoma and intracranial lipoma were consistent with ECCL. CONCLUSION: Since the skin and ocular manifestations can be easily observed at birth examination, pediatricians and ophthalmologists should be aware of this condition...

Ectopic lacrimal gland, being one of the choristomas, is comprised of lacrimal gland tissue outside the lacrimal gland fossa in the fronto-lateral part of the orbital roof. Ectopic lacrimal gland is a rare condition where the gland may be found in the orbit, eyelids, ocular adnexa or within the globe. Neoplastic transformation of such tissue may occur. A sixty-two-year old male patient presented with right eye proptosis and slight nasal displacement of the globe. Computerized tomography scan revealed a well-defined hypodense lesion of size 19 x 18 x 20 mm supero-lateral to lateral rectus muscle, with mild proptosis and thinning of the right lateral orbital wall...

This report describes the histological and immunohistochemical features of multicentric, benign, epithelial inclusions (BEIs) in a free-ranging, adult, female Risso's dolphin (Grampus griseus). The differential diagnoses included ectopic hamartomatous epithelial inclusions, non-Müllerian choristoma, Müllerian choristoma and low-grade metastatic carcinoma/mesothelioma. The most likely diagnosis of such BEIs was multicentric, embolic, reactive mesothelium, as suggested by cytomorphological and immunophenotypical features of the BEIs, the occurrence of focal pleural rupture and the immunophenotype of the pleural mesothelium...

A 3-month-old, male European shorthair kitten exhibited an ill-defined, soft mass on the skin of the frontal head, which was present since birth. The surgically resected tissue was representative of a discrete dermal and subcutaneous mass comprising islands of neurons, glial and meningothelial elements, sometimes atypical or dysplastic, separated by dense collagenous connective tissue. There was no evident connection between this tissue and the brain. Immunohistochemical examination confirmed the presence of neurons and a pleocellular glial population, supporting a diagnosis of cutaneous neuroglial choristoma believed to be secondary to sequestered (resolved) meningoencephalocoele...

Neuromuscular choristoma (NMC) is a very rare, developmental malformation characterized by the endoneurial intercalation of mature muscle fibers among peripheral nerve fibers. NMC typically arises in the major proximal peripheral nerves, most commonly the sciatic nerve, and may involve the lumbosacral and brachial plexus. Patients present clinically with progressive neuropathy or plexopathy. NMC is strongly associated with development of a fibromatosis, histologically identical to conventional desmoid-type fibromatosis (NMC-fibromatosis)...
