Rhino-orbital-cerebral and pulmonary mucormycosis are acquired by the inhalation of spores. In healthy individuals, cilia transport these spores to the pharynx and they are cleared through the gastrointestinal tract. In susceptible individuals, infection usually begins in the nasal turbinates or the alveoli [ 7 ] In the latter, about one third of the patients have synchronous or metachronous bilateral tumors; multicentric paragangliomas may occur outside the head and neck region. CBP has been described in Carney's triad (extra-adrenal paraganglioma, gastrointestinal stromal tumor (GIST), and pulmonary chondroma) (Carney, 2009). Jugulotympanic paragangliom Pathology On gross appearance, the lesions can vary from 4 to 20 cm in length [ 1] and are covered by a fibrous pseudocapsule that is continuous with the underlying periosteum [ 7 ].

Pulmonary Hemosiderosis • Represents iron deposition in the lung secondary to recurrent episodes of pulmonary hemorrhage. • Two types: - Primary ay be idiopathic or associated with vasculitis- m • Appearance: that of pulmonary hemorrhage, with diffuse groundglass and often septal thickening. May progress to pulmonary fibrosis they can arise. These include Carney's triad, in association with paraganglioma and pulmonary chondroma, as well as Carney-Stratakis syndrome or dyad, an association of GIST with paraganglioma alone.15 As a rule, these Carney syndromic GISTs are deficient for SDHB Most gastrointestinal stromal tumors (GISTs) are driven by KIT or PDGFRA-activating mutations, but a small subset is associated with loss of function of the succinate dehydrogenase (SDH) complex of mitochondrial inner membrane proteins. This occurs by germline mutations of the SDH subunit genes and

Parosteal Osteosarcoma. Parosteal Osteosarcoma is a malignant, low-grade, osteosarcoma that occurs on the surface of the metaphysis of long bones. Patients typically present between ages 30 and 40 with a painfless mass. Diagnosis is made radiographically with a heavily ossified, lobulated mass arising from the cortex with biopsy showing. pulmonary chondroma and adrenal cortical adenoma (with at least two of these tumors in the patient by definition). Based on a review on 79 such patients by Carney [12], all GISTs were gastric. The tumors often occurred at a young age (mean 20 years), and there was a striking female predo-minance (85%) and a majority of tumors had an indolent. Benign extraosseous cartilaginous lesions are uncommon and usually present as tumorlike masses. In the past, the term soft part chondroma or extraskeletal chondroma was used arbitrarily for small, well-defined, solitary nodules of hyaline cartilage that are unattached to bone and occur primarily in the distal extremities (especially the fingers and hand) Acute interstitial pneumonitis. Dr Bruno Di Muzio and Dr Yuranga Weerakkody et al.

It mainly develops at the extremities (96%): 72% in the upper limb and 24% in the lower limb Chordoma. Chordomas are malignant tumors of primitive notochordal origin that most commonly occur in the sacrum and coccyx.

Soft tissue chondroma. Three subgroups of chromosome rearrangements were observed so far: 1) rearrangement of 12q13-15, 2) trisomy 5 and 3) loss 11q21-qter. Different HMGA2 involvements were reported on those chondromas with 12q13-q15 rearrangement, varying from amplification, truncated or full length HMGA2 transcript and HMGA2-LPP gene fusion. Mesenchymal tumours represent one of the most challenging field of diagnostic pathology and refinement of classification schemes plays a key role in improving the quality of pathologic diagnosis and, as a consequence, of therapeutic options. The recent publication of the new WHO classification of Soft Tissue Tumours and Bone represents a major step toward improved standardization of diagnosis

In most circumstances, it is a misnomer because a mass actually exists, and hence, the term pseudoneoplasm would be more appropriate. However, there may still be circumstances in which the term pseudotumor is applicable, and some scenarios are.

Studies generally concur that the phalanges and metatarsal bones are the most frequently involved pedal sites Osteopetrosis. Question 1 Explanation: Paget's disease is possibly caused by a paramyxovirus infection of the osteoclasts of the affected bone. It can be monostotic or polyostotic. It is characterized by an imbalance between osteoclasts and osteoblasts.

A hamartoma is a noncancerous tumor made of an abnormal mixture of normal tissues and cells from the area in which it grows. Hamartomas can grow on any part of the body, including the neck, face. Likewise, the distinction between benign or malignant is difficult unless metastatic disease or frank invasion is present. Most GISTs are sporadic, but these tumors can be associated with neurofibromatosis (NF-1) and Carney triad (gastric GIST, pulmonary chondroma, extraadrenal paraganglioma). GISTs are usually solitary, often large, round. Poorly differentiated squamous carcinoma, adenocarcinoma and large cell undifferentiated carcinoma. The WHO classification of lung cancers describes a spectrum of appearances for these tumours and diagnostic criteria for recognition, but with more poorly differentiated tumours the salient features may be relatively focal and a careful search of several blocks may be necessary to establish a. Chondrosarcoma (CHS) is the second most common primary malignant bone sarcoma.

The intra-adrenal and extra-adrenal paraganglia and the sympathetic nervous system are intimately associated during embryonic development and arise from the neural crest. The cortical anlage is invaded on its medial aspect by primitive sympathetic cells (PSCs) and nerve fibers that originate from the contiguous prevertebral and paravertebral sympathetic tissue in the 14-mm embryo. The pharynx is a passage common to the digestive and respiratory tracts.
