==Overview==
Multiple myeloma affects not only the bone marrow, but also spreads to other organ systems. This therefore, requires a detailed assessment of various organ systems. A number of times, any of these physical findings may warrant a further evaluation, and thus leads to an incidental diagnosis of multiple myeloma. [[Pallor]], [[purpura]], signs of [[cord compression]], [[hepatosplenomegaly]], bony pain without tenderness and [[carpal tunnel syndrome]] are some of the most common physical findings, in a patient presenting with multiple myeloma.

==Physical Examination==


'''Head, ears, eyes, nose, and throat (HEENT) examination:''' [[Pallor]] is one of the most evident physical findings associated with multiple myeloma. Additionally eyes may show exudative macular detachment, [[retinal haemorrhage]], or [[cotton-wool spot|cotton-wool spots]].
===General appearance===
*[[Multiple myeloma]] patients often appear [[lethargic]] and [[Fatigue|fatigued]]


'''Skin:''' [[Ecchymoses]] or [[purpura]] from [[thrombocytopenia]] may be evident.
===Vital Signs===
*Low-grade [[fever]] may be present


'''Central nervous system:''' It includes altered sensations, dermatomal sensory loss resulting from [[cord compression]] and neuropathy, myopathy, a [[Tinel's sign]], or a [[Phalen's maneuver|Phalen sign]] due to [[carpal tunnel syndrome|carpal tunnel compression]] secondary to [[amyloid]] deposition.
===Skin===
*[[Pallor]]
*[[Ecchymoses]]
*[[Purpura]]


'''Gastrointestinal system:''' [[Hepatosplenomegaly]]
===HEENT===
*[[Lymphadenopathy]]
*[[Conjuctiva|Conjuctival]] [[pallor]]
*[[Visual]] defects
*[[Exudative]] [[retinal]] detachment
*[[Retinal haemorrhage]]
*Increased [[adipose]] deposition around the [[neck]] (if [[dexamethasone]] is used for therapy)
*[[Cotton-wool spots]] may be present


'''Cardiovascular system:''' [[Cardiomyopathy]] from plasma protein deposition.
===Abdomen===
*[[Hepatomegaly]]  
*[[Splenomegaly]]
*Abdominal tenderness (if hypercalcemia is present)


'''Bony and muscular system:''' Pain without tenderness is a feature highly specific for multiple myeloma, though not diagnostic. Pathological fractures are also pretty common.
===Skeletal===
*Bony [[tenderness]] along [[cervical]], [[thoracic]], and [[lumbar]] [[spine]]
*Bony [[tenderness]] in long [[bones]]
*[[Tinel's sign]] may be present
*[[Phalen's maneuver|Phalen sign]] may be present


[[Plasmacytoma|Extramedullary plasmacytomas]], which consist of soft-tissue masses of plasma cells, are not uncommon.
===Neurologic===
*Dermatomal [[sensory loss]]
*Altered [[sensation]]
*[[Neuropathy]]


'''Amyloidosis''' may develop in some patients with MM. The characteristic physical examination findings that suggest amyloidosis include the following:
===Psychiatric===
:* Shoulder pad sign - Fat deposition around shoulders.
*Mood alterations (if [[hypercalcemia]] is present)
:* [[Macroglossia]]

:* [[Purpura]]

Overview

Patients with multiple myeloma usually appear fatigued and lethargic. Physical examination of patients with multiple myeloma is usually remarkable for pallor, purpura, hepatosplenomegaly, bony tenderness, carpal tunnel syndrome, and signs of cord compression. Any of these physical findings may warrant further evaluation, and thus lead to an incidental diagnosis of multiple myeloma.[1][2]
