botryoid

42 Inflorescence (0) solitary flower (or occasionally with 1-2 lateral flowers), (1) botryoid, panicle, or thyreoid (monotelic), (2) raceme, spike, or thyrse (polytelic).

When anterior urethral pathologies are examined, congenital urethral polyp in the anterior urethra, fossa navicularis pathologies (stenosis, Guerin's sinus), anterior urethral valve, syringocele (dilatation of Cowper's gland ducts), congenital bulbous urethral stricture, condyloma accuminatum, and especially botryoid sarcoma polyps should be taken into the consideration in the differential diagnosis (5,6,7,8).

The majority of cases fall under the embryonal subtype which comprises botryoid and anaplastic variants.

Cysts most commonly showing such epithelial theques are the gingival cyst of the adult, lateral periodontal cyst, botryoid odontogenic cyst, and sialodontogenic cyst [3].

The mass appeared to be several combined structures that looked botryoid (Fig 2).

Embryonal RMS consists of two subtypes, including botryoid RMS and leiomyosarcoma.

Embryonal variants include leiomyomatous RMS that is predominantly of paratesticular origin and the botryoid variant with subepithelial aggregates of tumor cells known as the cambium layer [14].

Botryoid cysts are characterized by a multilocular histologic finding and a higher risk of recurrence than lateral periodontal cysts.

Horn and Enterline in 1958 devised the first classification based on the pathological features into Embryonal, Botryoid, Alveolar and Pleomorphic subtypes.

Embryonal RMS has three variants, botryoid variant, spindle cell variant and anaplastic variant.

Eventually, after a scan showed a blockage, it was discovered that Jayden had a tumour in his bladder and he was diagnosed with Botryoid Rhabdomyosarcoma, an extremely rare form of cancer.
